loudest, throatiest exhaust possible.
 

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
