Thread: flowmasters

yeah u NEED a ressy or a glasspack or it sounds like throw up if throw up had a exhaust tone.. lol

ya the mechanic at the exhaust shop kept trying to tell me to let him cut off the resonator. i was like man its a grand prix, not a honda, the resonator stays! haha. sounds good tho with no mufflers and a stock res. very throaty, and a lot deeper than i expected out of a 6 cylinder. my buddy asked me if it was an V8. i took it as a compliment.

TB SS without a Res FTW!

I like not having that ugly resonator hanging behind the rear valance, it improved the looks IMO.

For now all mine has is no Res and a Flowmaster 40 Series 2 chamber in place of the stock muffler. It sounds great, LS2 is a great sounding motor. I plan on changing it up in the future, probably to a full cat back, we'll see.

thats tbss.... thats like a murder weapon on the streets haha tbss ftmfw!

On my next...muwaaaaahaaahahahahahahaha!!!!....(sorry) GP, I will put in a Thrush glasspack - IMO, that is the only one that has a decent sound. You all need to realize - no matter what you do, or what you spend - a V6 will never sound like a V8. Just like a Honda or Yamaha will never sound like a Harley.

That being said - the resonator must go on ANY GP that does exhaust work, and a glass pack must be installed. It is so written...and so it shall be.

haha you just found out?? what did you think you had? . and i still have my stock res but no mufflers, and I mines drones a lot too. But i kinda like it!

lol i had no clue. i rotated my tires yesterday at work and i could finally see the top of the muffler.

well i suppose its always better to find a couple flowmasters then maybe the mufflers off a miata or something? haha

haha yeah it was a pretty nice surprise

or a pt loser lmao

This thread has me very confused... Cause if no mufflers sounds good I'd rather go with that. It's alot cheaper and just looks better IMO. But some people say it sounds like rice and I should get flowmasters or somethin. Does your no muffler setup really sound good? Did you lose hp cause of a loss in backpressure? (mind you I own a GT)

i gotta call b/s on the no muffler sound! i have a pretty good leak behind the resonator, and it doesn't sound that good!

Huh? ^

you NEED mufflers for a good tone. the exhaust note that these cars make, resonator or not, is trash. you have to have some sort of muffler to create some form of an exhaust note.

like i said, this whole topic is very opinionated. some ppl say straight pipes all the way back, some say stock everything. Most have a fav resonator and muffler combination. Personally, I run a stock resonator with no mufflers, and I think it sounds f*&^in awesome. But I'll admit on the interstate it drones. Here's a link if you want to hear mine:

YouTube - Grand Prix GTP Exhaust

I say cut the mufflers off and run it like that for a few days, if you like it great, if not through a couple flowmasters on. (Or w.e muffler). That's what I did, and ended up with leaving the mufflers off.

Sounds pretty nice IMO, you would think Itd be louder tho.. I heard a 97-03 without mufflers and it was super loud

You'll come to find out once the mufflers are gone your going to hate it.

Idk like I'm not one of those people who are gonna ***** because it drones a little
