stock exhaust i removed the resonator and put a glass pack still pretty quite. i want to start modding it. i want to put a 3in down pipe. can anyone tell me how loud this thing will b??

its a 04 GTP comp G

what will change the tone is the mufflers and resonators

so w/ the glasspack it will becomre more throaty,

here is my exhaust from zzp w/ a thrush glasspack

_________________

yeah i got a thrush glass pack to . but stock mufflers so a down pipe wont change much witch is fine with me just want better air flow!..

save up an extra 40$ and get some headers

_________________

yeah. does zzp make any. and would headers come with a downpipe?

zzp headers are like 700+
i have speed daddys and they are 200 somethan on ebay and work just the same

and yes headers come w/ a downpipe so it will bolt up to the catback portion of your exhaust

_________________

niceeeee. hows the car perform after u put the headers and downpipe in??

speed daddy dont make any headers for a 04 GTP comp G

on grandprixforum there was a bunch of 04+ w/ speed daddys

and my headers are in my trunk

_________________

my old car i noticed a diffrence. the speeddaddies are SLP headers but made of a better stainless steel.

my car was a topswapped xp cam set up with out headers it made 261 wheel HP with was with a DP and stock manifolds. after the headers it made 280 wheel hp after some tuning.

becuase these runs where taken on diffrent days take that as you will also the car was modded so the gains are more then what they would be on a stock car

well i got something to look forward to lol

Through stock muffs not sure if it will be much louder but definitly has a deeper tone. I have a front plog and 3in catless DP and can tell a noticable differance in tone and a tad bit louder but nothing crazy since its still flowing out the stock exhaust, but when i get on it hard to hear much over the wicked exhaust leak i have where the dp bolts to the res.

The headers are all the same for any 3800 car. So 97-08 GP headers with the 3800 engine will fit. Speed Daddy isn't going to list a special trim level which doesn't have any effect on engine changes.
So just find some of those and enjoy
