Magnaflow or borla cat-back
Borla.... Magnaflow sound good though but if you want something louder then get the adjustable Borla system. I mean the passenger side piping is basically a straight pipe & the driver side piping goes through the muffler.
H/C cars is where it can start to get a little ridiculous.
I have a stock motor with longtube headers and no cats. When I first intalled the GMMG, it was loud and mean sounding. However, between 2k to 3k RPM, it sounded very raspy and crackly. I read on this forum and someone had used the chambered exhaust powerstick muffler to eliminate the rasp. I ordered one the next day and when I finally installed it, I no longer had the raspy annoying sound within the 2k-3k rpm range. It also made it a bit quieter but it deepened the tone. In my opinion, the powerstick muffler in the I-pipe definitely works.
