Recently a good friend of mine installed a Magnaflow X-pipe and cat-back on his 00' GT.I must say that I do not like the exhaust tone, it sounds like a 350 chevy or somekind of truck with exhaust. This has me re-thinking what exhaust system im going to install, right now im thinking Borla or maybe Bassani (if possible). Also i saw a 03 cobra with flowmaster exhaust and I must say that it sounded wicked.
