Dynomax Bullet Review

[1988 GMC 355]

Well Tuesday I had my Bullet installed. I had a Thrush welded and a tip out the side.
I switched it up this time I went with a 3" SI/SO 18" long bullet.
I have a single 3" tailpipe out the back tucked up close to the stock location
I also have Longtube headers. 2.5" custom y pipe and 3" Si/SO high flow cat
it drones just a wee bit less than the old setup, it deff is different compared to a chambered muffler
I love the sound though, it is amazing and just loud enough and is great.
it sounds different when its all cold compared to all warm.


I will have two vids tommorow promise :D

[Rye 21]

badass!

Waiting for vids

[GmcCountryChevy]

Definitely can't wait to hear how this sounds!!

[Low97tahoE]

Definitely can't wait to hear how this sounds!!
:word:

[CountryChevy15]

gona sound like crap, just take them off and send them to me free of charge.
















:lol:

I have heard these on a obs, not with the extensive setup you have but they still sound really good, and im sure with the extra work you have done they are going to sounds like :boobies:

[Static 90]

I like the way mine sound. They are even better with 3.5x14 tips now.

[1ugly88]

subd for vids

[Static 90]

I have a video in my webshots album without the tips. This weekend I will make one with the tips. I am curious to hear the OP set-up.

[uno99]

Bullets sound amazing

[1988 GMC 355]

I am trying to upload them now they take forever to upload :lol:

but yes they do sound pretty dam good IMO

[1988 GMC 355]

Sounds as great as I expected it to! Great sounding truck man !

[Static 90]

Sounds great! Nice looking truck too.

[1988 GMC 355]

thanks guys!
I love it so far and have had a few compliments I just wanna hear someone do a drive by with it so I can hear it

[JS 45]

that sounds good.. i like bullets thats what i have on my truck. that thing really doesnt sound like a 5.7 in that video. sounds different more like a strait piped 5.3 but maybe thats just me

[Low97tahoE]

damn, sounds good dude

[silverado_lover]

that sounds good.. i like bullets thats what i have on my truck. that thing really doesnt sound like a 5.7 in that video. sounds different more like a strait piped 5.3 but maybe thats just me

yeahhhhh bro thats just you...that bish is throaty!

[JS 45]

http://www.youtube.com/watch?v=XY5BBUoMDp8 sounds similar to this to me... i like the op's sound not knocking on it but it does sound a lot different than mine.

[1988 GMC 355]

well I deff dont have a 5.3 lol
but I do have longtubes, all mandrel bent pipe and a high flow cat.
I love the sound, it still has the same low end like it used to which i am very happy with.
shoot I out ran a durango last night and he even had a jump on me

[6.0 Bowtie HD]

Really? a durango you outta be pretty proud of your self. I always see them tearing up the local spots. J/k sounds great. Kinda makes me want to have a nice OBS.

[1988 GMC 355]

lmao, just saying. im not sure if ur being sarcastic or not.
But Thanks.

[addiction2bass]

o ya the bullets i love. i got two 18inch long 2.5bullets on my truck, keeping it true duals out the back with 4inch long tips. i love the sound of them! it does drone alittle BUT thats why we got stereos... just crank it up alittle more :) and i love bass so it never bothers me unless pops is in the car with me and he doesnt like the loud bass.lol
it pops quite a bit when just reving it in park but when driving it only pops when you realy get onto it hard! and then it sounds sweet ;)
i still have yet to get a driveby video as well. i keep meaning to get my brother to hold the camera and drop him off down a country road to do a nice one :)

sounds good!!
and I totally agree man, the drone is bearable and it does pop a bit but just enough to make me smile when u take off hard when the pipes are still kinda cold.
I love it and it sounds so good with headers, and for 46 bucks you can't beat it


Yea I was being a little sarcastic about the Durango comment. Seriously you have some time in on that truck and it sounds good looks better.

hahaha I fig, well it made me happy lol
But thanks alot I do have a lot into it and am happy so far.

[addiction2bass]

o ya the cost of them and just there size YOU JUST CANNT BEAT! hell who cannt cut out a section of pipe and clamp in these bullets ;) its INLINE with the pipes you have so theres no WILL IT FIT or IS IT THE RIGHT OFFSET to worry about :)
if you got a straight length of pipe you can squeeze one of these in. ;)
i put some little turbo mufflers on my old impala and after i put these bullets on my truck i knew i was going to replace my impalas turbos with these bulelts it just sounds so nice. quite at idle and comes alive with throttle. plus my impala could use all new pipes anyways ;) i scabbed the pipes up there pretty bad about 10years ago putting true duals on her.lol time for some professional pipes ran.
but i will be going with the same size bullets on my impala. i think the extra length helps more with the drone and poping with them being longer. so 18s will be used on the impala as well.

[1988 GMC 355]

yes the shop I always go to put mine on and the tailpipe for $85.
I need to slash cut it some stilll but I love how it idles then when you get on it it comes alive.
and I agree the 18's arent much quiter than the 12's I bet but the extra length helps with drone and pop.

Does your truck have an H-pipe and the stock cats? I was thinking about going dual Bullets on mine with a y-pipe to keep the stock tail, or maybe going dual tails, not sure. If I go duals I need an H-pipe to hopefully cut down the popping. Not sure I want to change it, doubt i'd be able to get my money back on the Magnaflow so I may just keep it and hope the cats clog so I can get highflows.

[addiction2bass]

mines got stock pipes upfront. i just cut off my stock muffler and put the bullets on it and had new pipes ran back to keep it true duals. no crossover pipes.

[SierraDan]

I couldn't stand my glasspacks on my old truck until I put the H-pipe in, much cleaner and deeper sound.

[1500 paul]

Awesome! Just listerned to the vid. Just found a pair with approx 24" +/-, 2-1/2" pipes and collector flanges. Package for 60 bucks. Will bolt right to my 50 buck Hooker LT's. What do you think??

sounds like a deal to me, my single 3" was 46 plus shipping

[1500 paul]

I'll prolly run them on out the back like i have now...... true duals, eventually, but it will let me mount headers right away and have some good sounding mufflers, if not loud ones! Might be a cab full of noise, but I think I can deal with it for a while.

I was wondering that myself...looks like everyone is goin with 18"s, any idea what length does in relation to sound output if not actual volume?
I would assume length would mean more of an even tone with less cracking...right?
Im torn between dual 12's or 18's for my truck, wish I could hear a truck equipped with em in person:confused:

yes much more toned and less pop, it depends if you have stock cats and manifolds?

if I had all stock stuff like that id got 12" but with my LT's and high flow cat a 12" would be way to loud for me

Well my killer deal for 2 @ $60 bucks went out the window. Guy changed his mind, nutsack! Can't say I blame him though. Oh well, I think I'm hooked now. The search will continue:)

I've been doin research so that I can do my exhaust system right...Im a bit of a perfectionist haha
Plus three more guys at my school bought obs chevys too so I MUST have the best sounding truck!
My plans include longtube headers, HF cats with 2 1/2 true duals and a X-pipe goin out at 45's with 18"x3" tips...
I also plan to do engine work and Im shooting for 300+hp with more power in the upper mid-range so my exhaust system is heavily dependant on performance.

[SierraDan]

For the best sound I recommend real muffler, Bullets are designed as resonators. They can sound good but personally with headers and highflow cats I think they're not toned enough for a clean sound. I would try a Spintech, or an Aero Turbine, or if you like loud but want a deeper, cleaner sound try a Pypes M80.

[1988 GMC 355]

I love mine and all but I think I lost some velocity in my system and some MPG too

plausable ??

[addiction2bass]

mpg loss... well yes BUT NO. your loosing mpg because you like to hear the rumble ;) hell i lost 2-3mpg when i got mine on. but i played with it alot on the throttle.lol now that ive gotten used to it im back to a solid 16mpg typical with normal driving which is typically speeding still ;) like 80-90mph to work on the interestate at 5am ish so very little traffic with still a 50/50city highway driving style. when i did my round trip to florida all highway it was something like I THINK 19-20ish cannt remeber off hand since thats been over 6months, might have been more. i know it was alot better all highway :)

like any engine mod or tweak you do you tend to peddle it harder for the first month or so ;)

[1988 GMC 355]

haha well I know that but I have driven like I usually do and went on a all hwy trip last week and got worse MPG then I did last year and I didnt have ,e fans, chip last year

so I am wondering if my loss in velocity could affect it that much

How well do you think the dual bullet system would work, would I lose velocity and power?
Does anyone have links of bullets on a truck with longtubes and/or HF cats?

[SierraDan]

As long as the pipes are sized correctly, then you won't lose anything. For 300hp, I recommend 2.5" pipes to keep low end and for enough flow to attain all that power when you get on it. If you're really set on Bullets, go with the 18" for the deeper sound, and get a crossover for an even deeper, smoother tone.

Ya, I was just hoping to see if/how the sound would change with duals and crossover

If I were you I'd get a Spintech Pro Street...I just got one and it sounds amazing and as performance goes I hear the Spintech is just an all out performance muffler.

Link in my sig is an exhaust clip and if you look through all my other vids there are a couple of inside sound vids

dont you be whorin up my thread with that expensive good sounding sh!t :lol:

I really cant hear much of an 'improvement'...?

[JS 45]

yea she only does that every now and then most of the time it starts right up..... as for spintech there is no way they can be considered "performance" google spintech cutaway muffler and look whats inside of those things.,, cant be any better than a flowmaster or any other chambered muffler

[SierraDan]

Actually Spintech mufflers maintain flow with the swirls, they spin the air which increases the speed, they work like Vortec heads in that sense.

Interesting...ever since I switched from a Blow 40 to Spintech I've gained gas mileage, truck is noticeably quicker, and now the tires chirp when it shifts into second. Thats better than Chokemaster to me but what do I know :dunno:

[98silvyman]

but what do I know :dunno:

you know that i should switch my muffler :dunno:

open up a stock 99+ muffler...they have the same circular baffles next to each other, except they lay on the side....and that supposedly flows good....i know one thing....a stock 2010 camaro muffler is a like a performance muffler, and a guy that owns a local exhaust shop switched to spintech on his new camaro and saw a 4hp increase on the dyno....id say thats performance....plus, a truck would see a bigger increase because it has a more restrictive muffler....and an even bigger increase when switching from a flowmaster since those piles make u lose hp

[11ellswrob]

This is why I wanna see some trucks in person!
Its so hard to figure out how the truck actually sounds over the internet because of a hundred factors like different cameras, wind, excess noise, poor quality speakers...
How much do spintech mufflers cost?
EDIT
Plus Im kinda ocd with things like this and it has to be 'perfect' so any little thing is gonna drive me crazy every day, so if I end with a sound I dont like Im gonna be agitated every day lol

[JS 45]

i think its funny how all you guys think changing the muffler makes your truck so much more bad azz.. i went from a flowmaster to a dynomax bullet no change and if there was it was so minimal that i couldnt see it.

[addiction2bass]

But the butt dyno don't lie ;) J/K

spintechs are like 85 or so a piece, depending on the model. Everybody likes a different sound, and whatever you buy, chances are youll become bored with it eventually. If I could have any muffler, id choose a Corsa, I think the sound is just the best. Spintechs sound pretty similar to them though.

[silverado_lover]

Wellllllllll I just got from a trip and got 17 mpg with half the tank hard city driving and the other half highway...with the flow I would get 15 mpg no matter if it was city or highway so there are some numbers to run through that tiny little brain of yours. Also you never rode in my truck before or after I switched mufflers so if you say anything about the performance of my truck you're point is invalid.

[JS 45]

Bada$$ sounding in our opinions is all that counts, we really dont give a fvck what anyone else thinks of our setup

I couldnt agree more... i run bullets like you. i like them. my point was saying just by switching the muffler some people believe their trucks have 1,000 more horespower

i think this is a joke. i dont believe that you can get the same mileage between hard city driving and highway driving just because of the muffler. that is funny. but if thats what you want to think that is fine.

[silverado_lover]

I'm not claiming much more HP but it is noticable enough cause I drive it everyday so I'm pretty aware of how it performs.

And who said I was doing any hard city driving with the Flow? Hell I usually didn't break 2000 RPM when I had it.

I used to get ~330 miles per tank and I just got ~370 miles outta my tank

[addiction2bass]

well with the milage there are so many factors you cannt say its just the muffler. it could have been you was just driving with the wind direction more or fighting the wind ;) the wind and tempatures out have alot to do with mpg than you think!
i drove up north in my old civic in the morning and with the wind most the time and on the trip back same day later in the afternoon and fighting the wind i lost like 3-4mpg on the trip back all highway.

Heh, in my '98 that I had, it had two 18's but the exhaust never connected between the two. Awesome sounding, simply put. No vid. :(
On my '00 I have two 12's split after the factory y connection and it sounds...well not the best. Sounds great at (cold) idle but not impressed at take off. If there is one thing I miss about my OBS, it was the exhaust.:(

Would the difference in sound be because of the difference in motor types?
All my research tells me that I need a crossover for the best performance so if a muffler actually sounded worse with one I would rather find a more suitable muffler than run it without the crossover.
Dang this is all so complicated, a week or two ago I thought I found myself a muffler now Im back to where I was before, wide eyed and clueless:looking:

[Stärke]

True, 5.7 vs 5.3. I wasn't expecting the same, of course. I've been thinking of losing the 16"x3.5" tips, though, and do something similar to the OP's setup. Which sounds great, btw.:D

Thanks I have always ran single 3" setups and love it alot, very deep and tone with just a but of rap on a hard take off and shift

[96z71GRNMACHINE]

Would the longer bullets sound deeper then the short ones?

[1988 GMC 355]

Yes they will be deeper and less raspy, tips will also make the sound deeper and more toned.

[addiction2bass]

ya i like mine. i think the shorter ones would be to raspy/popie and probably louder and more annoying.
i really like my dual 18bullets with nice tips sounds MOST THE TIME, but in all honesty sometimes its annoying at highway cruisin with my radio down low. but most the time i just turn it up louder. ;)

[billdaz99]

I have the same setup as addiction2bass i think, but with the 12'' bullets and 45's out the back w/ tips. It is loud and deep as well. I love it.

[setty7]

do dual 12's with an x pipe sound loud like straight pipes but just deeper and more aggresive? Thinking about the bullets, spintech 6000 or 9000 or a fm super 10?

[setty7]

yall post vids of the dual 18s and 12s plz

[ryan_thompson87]

Well I just ordered a pair in 16" flavour since I broke the cases on my flowmasters, Thanks, it reinforces my decision :lol:

[1988 GMC 355]

Lol my video is of a 18"


and good deal man!!! you wont be dissapointed at all! let me know how you like them

[addiction2bass]

yall post vids of the dual 18s and 12s plz

mines dual 18s heres my only decent one i think. my other one has wicked wind noise and ive just never made anew video. they still sound great tho maybe better with them out the rear and nice tips.

[setty7]

wheres the vid addiction2bass?

[1988 GMC 355]

even if he posts vids they won't be good enough for you to decide. IF you clutter my thread up much more then this I will have your posts deleted.

How is a Bullet different than a standard Thrush Glasspack? Both are a perforated tube with packing, but the glasspack is cheaper. What advantage is there of buying the more expensive Bullet? Is the inside larger or something?

[addiction2bass]

Well I've had those before on my impala... they sound good at first but in time they soundlike crap. Just not built as goold I guess. When I get my impala back on the road I want to get all new pipes and dual bullets just likemy truck on it.

[ryan_thompson87]

Just got my 12s in today, will be putting them on shortly. When I went to get the ends expanded so I can slip them over the pipe, the guy goes, "Jesus those aren't mufflers they're resonators" :lol: :run:

the inside of the Bullet looks like a cheese grater, no packing at all just perforated metal


Just got my 12s in today, will be putting them on shortly. When I went to get the ends expanded so I can slip them over the pipe, the guy goes, "Jesus those aren't mufflers they're resonators" :lol: :run:

THats all they look like :lol: you will love them though, they don't drone that bad either and can be as loud or quiet as you want them to be

[addiction2bass]

well at cruisin highway speeds they can drone with the radio down of course. but nothing a turn of the volume knob cant fix ;)
i still love em!

[ryan_thompson87]

Hmmm, well mine sound NOTHING like your guys do, Not at all what I was expecting.

how are they different? more pop?

[ryan_thompson87]

Sounds more like straight pipe, almost a lack of the tone and just loud. I think it may have something to do with the fact they are just right off the muffler right now, no tail pipes and turn downs on it. Hopefully that changes it.

Are you running cats? tailpipes and tips will help, you do have a cammed engine, headers, and those are only 12" long soooo

[ryan_thompson87]

:lol: Ya, That was the problem the only time I heard these were either on a full out race setup, or a pretty much stock truck. Nothing in the middle like mine. Hope the tail pipes help. I can hear where it wants to give a bark, but the loud just over comes it. Gonna crawl under and see what I would have to do to get my old tail pipes on, the Flows were center in offset out so they are off although they're the same length, I might be able to make it work. I did do a few runs down at the river bed I will say I sure like the sound of them when it's singing 5500 RPM slingin' clay :aniteef:

Well they can be tamed and toned and in your case you will need some tail pipes and some cheap tips to tone it down to a bark like mine, I bet that sounded flat out mean!!

[ryan_thompson87]

I have no problem with the noise level, just want some tone out of it. I'm gonna toss some tailpipes on it tommorow just to see if it helps. I'm sure it will some. I'll get some vids of how it sounds before and after.

[1988 GMC 355]

tailpipes out to the back will help as will some long tips to if you want, vids would be sweet!

[ryan_thompson87]

Well sweet jesus its one extreme to another. Got the pipes on and its insanely loud and reeeal raspy. Not sure how I feel about it still :lol: A bit too obnoxious I feel, well see. Vids to come.

[1988 GMC 355]

:lol: well you did go with 12's, you asked for it :lol: and maybe run bigger diameter pipe or some long big tips

[ryan_thompson87]

Well it honestly sounded much, much nicer dumped under the cab, so here's my new plan. Buy some cheap tips and and clamp them to the mufflers and under the box and see if I can achieve best of both worlds :lol:

Sounds like a great idea to me. :lol:

[ryan_thompson87]

Ok, finally got some videos, and also tore the tailpipes off, couldn't deal with it :lol: The camera doesn't do it justice, if it actually sounded like it does on the video I would like it, but it's much more poppy, but you can still kind of hear it. And the last videos are with the Bullets dumped. And yes, my truck is currently filthy, but the camera makes my windshield look impossible to see through :lol:

And the Dumped:

Camera died and didn't catch of that one.

Haha, sorry forgot to turn down my Corb Lund down on this one.


http://www.youtube.com/watch?v=VmyxaTDQZxM

I'll try to get one of it really screaming later, I only did about 3/4 throttle on that one, hard to drive and hold the camera :aniteef: They really do sound amazing singing up high. They are growing on me dumped.

EDIT: Lmao just noticed the screen shot on the last video, that's kinda cool.

[setty7]

sounds good! u just runnin a single bullet?

[1988 GMC 355]

Jeez dude read his posts on this page and the last, you really are dumb.

and well I hope you like it man, its poppy and raspy to me, but as long as you like it thats what counts, mine sounds like that when I am in the throttle hard shifting into second and i like that every once and a while.

[ryan_thompson87]

Like I said, if it had sounded like it did on the recording I would have liked it. When it would hit around 2500 it sounded more like my friends Artic Cat 700 with a pipe on it, not even like a truck.

[1988 GMC 355]

I don't doubt that, so you keeping them?

[ryan_thompson87]

Planning to ya. Picked up some 18" Magnaflow 3' stainless tips to clamp on and try for some moderate resonance, if not, just run them dumped.

[1988 GMC 355]

hopefully that ll help tone it down.

[ryan_thompson87]

Well the tips did it, I like the sound of them now :lol: Just the right amount and loud and some rumble in there to. Now just gotta get the pipes level underneath so the tips aren't different heights.

I figured the tips would tone it and take some of the rasp out, and ya thats a pet peeve of mine :lol:, glad you like them more.
