My ***hole exhaust idea backfired on me...

[MrMobley]

Well I had the intention of trying to run the loudest exhaust I could and I think I went above and WAY beyond my expectations. As the sig says I've got LT's straight to dual Spintech 9000's. It may just be that I have such a high stall speed that makes it worse but the exhaust is absolutely ear splittingly loud on take off. I'm trying to decide what to do, if I just put in a set of high flow cats will it muffle the sound of my cam at all? Because I'm already spoiled for it and can't give that up, any opinions on what to do? I love the exhaust just want to take the volume down a few notches. To put it into perspective of how loud it is, it sets off the alarms on my buddies trucks from around a block away... I'd say it's at LEAST 90% as loud as my open headers were.

Maybe you could install a few resonators on it to tone it down some. That should work, you can use any cheap glasspack as a resonator.

[mrhp]

Install an H or y pipe. That will smooth out the pulses and quiet the sound. It will also boost your bottom end power to boot.

[SUBURBIAN]

glasspacks.

[silverado_lover]

Add some cats and if that doesn't work I'd swap the 9000's for some 6000's

I would check around on forums and maybe you could find someone to do a straight trade

I'd say the main reason it's so loud is the cam

YOu also have dumps, bad idea if it is loud and resonating, you need to run it out the back, straight and just cut off enough so you cant see and put in some resonators/glasspacks to tone it down.

Wrong. Almost ridiculously wrong.

lolwut

Are you trying to say that a cam doesn't change the noise level of an exhaust?

Why don't you explain exactly how a cam (alone) makes an engine as loud as the OP claims.

Re-read what was posted...I didn't say alone, I said main. That same setup without a cam wouldn't be so ear splitting, but with one yeah it's going to be pretty damn loud.

Everything about that setup is working harmoniously to provide a fvcking loud exhaust.

OP did you at least watch vids on youtube to have an idea of what your truck was going to sound like?

Yup...the main reason it's so loud is the cam...that's exactly what you said.

Now, you claim the cam is a only a part of the setup...and it would still be ear splitting loud without it...just not "so ear splitting".

This cam is hardly "wild". You know that header type, headpipe diameter/length, muffler type/placement, tailpipe presence...all of these things are what make the tone signature of a vehicle.

same cam.

It's not the cam dude. Argue, say what you want... It is the exhaust that makes the exhaust loud.

[randeez]

if its to loud... you're to old :looking:

[silverado_lover]

I really like how you found four vids of vehicles idling and most don't even give specs on the exhaust :lol:

Yeah the exhaust setup will highly influence the sound but the cam still makes a fvcking difference. Just go look for vids of a car with the exact same exhaust setup except one has a stock cam and the other an aftermarket cam and tell me there isn't a noticeable difference in the sound level.

I found 4 videos in less than a minute, had nothing to do with specs, only sound. The details of the exhausts are irrelevant, only thing that matters is that all the engines sound different. ,,but the cam is the SAME. Do you think they all had the same setups? Of course not. I could show you videos of hotter cams with less rapping and crackling than the noisiest of the vids above...because the mufflers drown out more "sound". Leave everything the same and change cams, what happens? Does it sound like a cup car now?

yep

[MrMobley]

Haha well, I'm not worried about it resonating at all, and I don't want it to be "just not as loud inside the truck." I'm really trying to cut down on the attention I get from the men in blue (not the blue man group before someone says that). I'd like to stick with the 9000's for now and just try adding some cat's first.

On a side note, Suburbian are you stalking me? Seems like everywhere I post you're right there behind me.

And even though you are very blunt about ****, it's nice to see posts that teach me something instead of just random he said she said B.S. no offense intended to anyone in this thread.

I offer advice. I try to assist the members on this board with things that I can help with. Nothing more.

[MrMobley]

About all any of us could do really.

[JohnMatt]

You figure out what you're going to do yet? Thought it was going to turn into a pissing match several days ago so I stopped reading. I personally don't think cats alone will get it much quieter. Cats, resonators like a glasspack and an x-pipe would sound sweet but I've always been a big fan of x-pipes.

[oneloudz71]

I think cats will help and if that doesn't do it you could add in resonators, or you could add in resonators first, whatever route you want to try. When I did my exhaust I did it in stages because of time and also so I could try different setups. First I started with my stock truck and just cut the muffler and tailpipe off, louder but sounded like crap (it was no surprise to me). Next setup was Pacesetter LT's, no cats, Y'ed into a single 3" pipe running back to a single 3" in/out Borla XR-1 dumped before the rear axle. This was too poppy for what I was looking for and much too loud inside the truck for me. Next I ordered a single 3" in/out Spintech 6000, swapped that out for the Borla and didn't even bother taking it off the hoist because it was a similar volume to the Borla. I then put the Borla back on as a resonator, installed the Spintech about a foot behind the Borla and then ran a tailpipe out at the stock location. This last setup sounds really nice ourside to me and isn't too lound inside, I am happy with it for now. I am going to be changing the truck up quite a bit in the next year and the exhaust will be part of that. It will be ran out to the back and dumped right at the rear bumper, not sure what muffler and/or resonators I will use at that time.

[MrMobley]

I'm just rolling with it for now and seeing if it grows on me at all. Not really sure of a course of action yet.

[JohnMatt]

I used to like really loud setups but I got over that stage. Being almost 24 now I still like something with some volume but like a good clean sound for regular driving and cruising. Resonators with x-pipe would be almost perfect and still be loud when you get into it with those spintechs

[MrMobley]

That's what I like too, but the idea was to just to be as ignorantly loud as possible. And it came out louder than I expected.

[JohnMatt]

One of my previous cars was a cammed bolt on 04 GTO and for awhile I was running open midpipes so I can understand the loud factor. It was loud but I got used to it and the open exhaust really exaggerated the cam which was very similar to your 228r

[Low97tahoE]

id prob put a couple dynomax bullets in there, 12", that should help quiet the tone just enough

[Tigwldr]

I did the same thing on one of my previous trucks. Went from stock to JBA shorties, Magnaflow high flow cats and a 2.5" SI/SO Flowmaster Original 40 series muffler made into a 2.5" DI/3"DO exiting in front of the rear tire. My truck had no cam or any internal work, all bolt-ons and I was setting alarms off one to two blocks away. That lasted about a month. Swapped out the muffler for a larger Magnaflow.

You could always throw some tailpipes on it to. That will help with the drone inside the vehicle.

I would like to hear it. Do you have any videos of it?

[GreenVortec]

run short tips to the back, make it sound like a vette haha people would be like ..... "the fvck?!"

[XLR8N]

Just going to throw this out there. You also raise the idle RPM when you swap out cams generally.
