If i were to get a glasspack muffler like a cherry bomb to replace the stock resonator on an 04 gtp, what size would i get, and would it make a noticeable difference in sound?

Probably. How much is unknown. If you get one about the same size you might not notice to much of a difference. If you go any shorter it will get louder.Originally Posted by 04GrandPrixGTP

Longer the glasspack, quieter the car...and it'll sound better too...I stuck with my stock GM resonator and people ask me if I have a V8 all the time

Flowmaster 40's with the stock GM Resonator...but I have Pacesetter's, No Cat, and custom 3" Piping all the way back from the Downpipe...plus a lopey cam
06-30-2009
xp cam right? lol. i think that was in the video. well, i guess glasspack is ok on pipe. 3" all the way out if i plan on runnin 10lbs boost eventually?
06-30-2009
I want to get the 40's too. It seems like a lot of people don't like them but I love the sound of the flowmasters

10psi is weaksauce
Just keep the stock GM Resonator and save yourself some money...throw on some Flow40's and get a bigger Y-Pipe in the back...that'll give ya soundtake the cat out too...shouldn't cost you more than $200 IMO...if it does you don't have a good exhaust guy
06-30-2009
yea 10 psi is weak, go for around 18
06-30-2009
25 or bust p*ssy

well dang, how much boost will teh 3.25" pulley make? i thought it would be around 10-11 or so...
07-01-2009
Drop pullies last...what mods are you planning...3.25" seems way too small for headers and other small bolt ons
07-01-2009
Yup! I just tell all the ricer kids that I did a v8 swap. It's fun to watch them start counting...I stuck with my stock GM resonator and people ask me if I have a V8 all the time
I'm on a P-log setup with no cat, stock res and no mufflers. No rasp and not near as loud as you'd expect.
07-01-2009
Flowmasters Suck! They are overpriced and still restrictive only thing they got for them is a sound deeper than stock. They're just like Sony you just pay for the name.
Go Magnaflow you won't be disappointed.
07-01-2009
Also i can and have run 11psi on my 3.4" FWIW. Dropping pulleys isn't everything. You gotta have the mods to go with it.
07-01-2009
Well...unless your making over 350WHP stock mufflers are still good and swapping mufflers is only good for sound anyways...no ones buys them for a performance increase...
