does anyone like the MAC catback for the 99 gt's? anyone know how well it sounds? likes? dislikes? would it sound better with a h pipe or x pipe? only other mod i have is CAI.

 

Mac has a nice sound, but it will eventually rust on you especially the tips. Go with a Stainless steel setup.

 

SLP for the win!

 

i have macs with an offroad x. it sounds good but not loud enough. with cats it was almost stock sounding.

 

i got an 04 gt with the stainless steel MAC cat back and it sounds good. ive had it on for a while now, and there is no rust on it. and the whole system still shines up nice with a little polish. its just right if you want a better sound over stock. but not loud enough, if you want you car super loud. go with a MAC catback, stainless steel only, and the catted MAC prochamber and it will sound sick.
