So I know this has been beat to death already, but if I want my GTP to be just a little louder. My buddy has a '04 GP that he took the mufflers off of, it sounds ok but a little to loud for what I want. If I cut just the resonator of will that keep it decent sounding? I like a nice deep tone.

^at idle yes.

Get on the throttle, like revving it or driving and accelerating and it will sound like ass.

I'm looking at changing my mufflers, thinkin magnaflows from what I've heard. Anyone got the specs on what fits good or a part number would be great. I think everyone said they were 2.25 pipe but i'm not sure. Also considered Borla's but they sound pricey. All I'm looking for is a little louder but deep sound, without changing the whole system. Thanks!

i put flowmaster 40s on my car with just a dp and it sounds pretyy nice and not too obnoxious.. the sound will really depend on what you do like res delete or cat delete which some ppl think is obnoxious.. i personally like the sound with the dp and u bend delete w/ cat.. i was thinking of deleting the res but i dunno if that will be obnoxious...

[01gtpnoob]

fst i like the sound of that exhaust...
anyone have any suggestions as to what i can do for exhaust.
i got an 01 black gtp 4 door. i'll be getting window tints soon but
i wanna make it fast. i don't know what kind of exhaust systems
are good and how much power they add..
let me know. thanks

[fst]

thanks 01gtpnoob. but to be honest, stick with the stock mufflers as they sound very nice without the stock resonator/u-bend, stock cat, and 2.25" piping. just get a hi-flo cat, u-bend delete mod, increase the exhaust piping to 2.5" and get a decent resonator and you'd be set. my vs cammed setup sounded nice at idle but very crappy at WOT when i had the cutout open. now that im turbo'd it sounds way better both at idle and at WOT ;-)

[01gtpnoob]

should i just buy a whole new magnaflow exhaust system or something?
would that be easier? or should i mod the parts like you said.
and i know that this sounds stupid but could you dumb down what you suggested a little lol. as my name suggests i'm a noob when it comes to modifying something like the ride i got. i've had it for about 4 months and i want to beef it up so that it's more powerful, sounds good and kicks some ass

in garage part 1 (first put exhaust in)
YouTube - ‪2004 Pontiac Grand Prix Dual Flow Masters‬‎
in car (with CAI and PCM installed)
YouTube - ‪2004 Pontiac Grand Prix Dual Flow Masters‬‎

YouTube - ‪2004 Grand Prix Dual Flowmasters (Updated)‬‎

[tpsgtp]
