I have an 04 GT the only performance modification i have done is a flowmaster 40 series cat-back system. I want the system to be a little louder, and if possible gain a few ponies. This weekend im headed up towards summit racing and am considering buying this
x-pipe. Will it make it noticibly louder? also will it give me any HP gains that i can actually tell? Thanks.
