My brother will have his 99-04 GT soon and he wants full exhaust done, but it's gotta sound mean as hell. What long tubes should he get? And should he go X or H, and with what mufflers?

Thanks for all the help and feel free to add any other input.

Some good long tubes, any off road mid pipe and SLP loudmouth version 1 is the loudest its gunna get. no way around that, i have it and its friggin ridiculous, too loud at times and theres really no way to keep it quiet

+1 On the SLP catback, that shit is loud!

The SLP is loud, but it sounds like ass IMO I have BBK Lt's coupled to an OR H with mac pro dumps, and I love the setup

Ditto on the Lt's with an H. The dynomax race bullet mufflers dumped would sound nasty too. A buddy of mine has it on his 2v and it sounds like a nasty Hot Street car.

thanks guys, do you think the SLP LM will rasp a lot with long tubes and an ORH? Like it does on the LS1.

it is a little raspy with the X which is why im swapping to an H

an H pipe will sound like mean american muscle. id say go with some LT...really dont care which. an O/R and some borla s type (stingers) mufflers. on borlas website theyre called S types. but they sound absolutely insane. throaty and yet have a good tone and theyll make some noise. and put some cut outs in front of the mufflers.

+1 for the stingers. I have heard many 03/04 cobras with the stingers and they are just nasty

on my 97 GT i had the following


BBK LTs + BBK O/R H Pipe + MagnaPack C/B = :devil: :drive: wow it was the best sound ever. get that he will not be dissapointed

mustangs, unlike f-bods, pretty much sound good no matter what exhaust you go with, when I had my '03 GT I had BBk lt's, shorty orx, and an MRT catback with v-force mufflers and it was honestly the best sounding car I have ever heard(go to www.mustangracing.com), I miss the sound but yah check out their catbacks they are greay quality and not many ppl have them....

My 96 is LOUD!! Shorty FMS headers. Offroad Hpipe, SLP loudmouth. Its really loud

Ok I switched from the standard LT's, O/R H, and flowmaster dumped to LT, O/R H and dynomax race bullets dumped. OMFG! The filling in my tooth rattles it's that damn loud. When I go WOT baby Jesus cries!!!!!!!!!!!!!!!! This has to be the loudest exhaust eva. ;) -Mark

i would recomend Str8 pipe, but i have flow off road-xpipe and its pritty load... but my buddy has a 03 gt with borla and it sounds like a stock cobra, but my other buddy has a 94gt with str8 pipe and its the meanest mustang ive heard with out it being tubbed out~!
