do not do this flowmaster is a crappy muffler and your milage will suffer ,after i replaced my flowmaster system with dynomax ultraflow welded ,i had much better torque and picked up about 75 more miles to the tank ,run away from the flowmaster.once the ultraflow gets broken in its plenty loud.

trust me i had the american thunder and have seen the flow numbers to prove just how bad they suck
i went straight from a flow to the dyno max and the truck performed sooo much beter and made 245 hp on the dyno so thats how i know it works .i picked up 10 hp /12ftlbs just from switching from the 3inch in/dual 2 1/2 out the back system to a 3 inch single behind the rear wheel. i would tell anyone this if i didn't have the experiance.
ohh and i think mine sounds just as loud as my old flowmaster,i mean i had the relearn how to drive the truck cause it made so much more power down low i couldn't hardly pull out of anywhere without spinning the tires.

hummmmmmm, lets see, last vortec 350 ('98+) made 255 at the crank and you are putting 245 to the ground....................:think:
that's one hell of an exhaust you got there.
guess i need to go back to complete stock, i'm only dynoing (sp) at 231, hell i'm loosing power.:whatever:

You've gotta remember, everyone has a PERSONAL PREFERENCE when it comes to exhaust. Some like Flows obviously, some like Dynomax, some Like Magnaflow, Spin Tech, Bassani, etc etc etc.
flowmasters MIGHT not be the best thing since sliced bread for performance, but if I read his post right, he seems to be looking more for sound. Hell, why the eff do you think I put exhaust on all my vehicles? TO HEAR IT!!! I could give a **** about the performance. I mean hell yeah it's nice, and so is the mileage, but most people are looking for sound. Flowmaster has built their mufflers for sound and performance, but they seem to give a better sound more than performance. With each Flowmaster I've had installed on any of our vehicles or friends have had installed, they automatically noticed a difference. I did too. You've gotta look more closely at Flow Bench tests too, rather than "this ones got a higher number, SWEET!!!"
Some companies actually test competitors mufflers w/ a smaller inlet/outlet, and sometimes even test their as a true dual system rather than a single like the competitor. It doesn't matter how many cfm's they show, a flow bench ain't gonna give you real world results. A 400 hp motor w/ Flowmasters is pushing a HELL of a lot more cfm's through a Flowmaster than your basically stock 5.7 w/ an Ultraflow will ever flow, so it depends on a lot of factors.
I used to think Flowmasters were the best, everyone else sucked. I now like different mufflers for different applications and cars. And like I said, ITS A PERSONAL PREFERENCE THING!!!!!!!!!!!
So if you say my 454 suffered from mileage loss and a power loss, how in the F U C K did I gain 3 mpg freeway driving? OUT OF A 454? The firs thing I noticed w/ my 70 series was a hell of a lot more top end pulling up a hill. I didn't have any low end loss, but you shouldn't with a 454. And for your 5.7 being able to spin them that easily w/ even 245 horses, keep dreaming :whatever:
Lets compare my 7.4 ltr 454 w/ OH MY GOD THEY SUCK ANIS Flowmaster exhaus, intake, and chip w/ 4:10 gears and 265/75 tires, and w/e tires you've got, in a little burnout competition.
I know, I know, "YOUVE GOTTA 454 DUUUUUDE"

here is the sheet.and thats with 137,000 miles and i just now replaced the 4year old crappy napa plug wires with some taylors ,i checked the ohms and man what a differance can't wait to see how the ol gas milage does. i agree about personal prefferance ,but he came on asking advice so i gave it to him ,because i have been there i like the way flowmaster sounds ,but if i'm gonna put something on my truck like that it better make me some power.especially for the cost,i did a little reserch on the dynomax site got the part #s for the ultraflo welded muffler and tail pipe only from the kit and took a gamble and hoped that my y pipe from my flowmaster system would work on this new muffler and came out 100 bucks less that getting the complete kit and just welded it on myself.

trust me man i'm 34 years old i think i know a thing or two about muffler testing but not everything ,and any performance muffler is better and will give a differance that a stock muffler ,but you have to look and do some reserch as to what is going to give you the best of everything ,but when i bought my first 94 caprice with the lt1 and all it had was a set of ultraflows omn it i was hooked and started doing some reserch and looking around and found sevaral test the all showed flows at the bottom of the list as a matter of fact they where even slightly lower that the edelbrock mufflers ,if all you want is sound thats great ,but like i said for my money i'd like a little of everything,sound doesn't win races. and neither des my single tire frier..lol i need to get my 3.73's and posi installed..lol .i'm not here to start a fight ,just want folks to be informed and not be mislead by the "everyone else is doing this" theory .otherwise we would all be driving hondas with a 5 inch tip feed by a 1 1/4 exhaust...lol

245 is possible from a 350, but no bolt on's (blower considered a bolt on LOL) are gonna give that much. on a NA 350 you will have to open the block to gain that much power. sorry, but that dyno can not be right unless he is giving you est crank HP (what year by the way?).
spinning tires, any V8 powered 4x2 truck running normaly can spin the tires. with a light bed, not a problem. i can't get on mine hard on take off, tires have a 12" wide tread and easily spins (with hardly any effort) and i still have 3.42's.
not knocking his choice on muffler (hell we sell dynomax)

sorry, i just find it hard to believe you gained 50-60HP with just headers/muffler combo. and gained 10 of that with just a muffler change. so before, whenyou were at a measly 235 RWHP, you had no low end torque? just doesn't add up.

i don't know what it put out stock ,the flowmaster was the first mod ,other than descreening the maf and a k&n filter that i did like in the first week ,i've had the truck for 4 years now it had 52,000miles when i bought it when i bought it it was stock right down to the crappy tigerpaw tires but i gained 10 hp from just swaping from the flow to the dyno.i don't have a tune cause till i stumbled on to this site i couldn't find anyone to even touch a 95-98 vortec computer and still no one close by knows how ,i mean christ a brand new ls1 and ls4 can be tuned but not a vortec ..lol so i just have to save a few pennys and send it off to where ever that one guy that does tune em lives and thats an assload of money for that ,i just mainly want the fuel shutoff removed i'd prolly make a little more power after that but it just seems to be pulling the hardest right when it shuts down..lol and i'm usually taking whoever i'm racing up to that point. lol so it looks bad..

'96 & '97 vortec's put out 250 at the crank. i've seen dyno's read 180/200 at the wheels. depending on dyno (usually closer to 180). westers and other make custom tunes for your computer. but the results i've seen with bolt on's and custom tune are about where you are now.
back to the original question. just don't buy a glass pack. if you only want loud, i hear bullet's are pretty loud.

Personally, I have the Flow 40 because it sounds badass :D
If I wanted a quick truck, I wouldn't have bought a EC 4x4 :santadeer
I was bored :crazy:
You should be jealous Joe, Flowmasters manufacturing plant is about 15 minutes from my house :LOL:
