Im really leaning towards throwing an exhaust on my MAX. Sux it is so expensive though. I know Greddy is probably the best way to go. What is the difference between the Greddy SP2 and the EVO? I was thinking about just a Powertech Muffler. Heard some sound clips, and the sounded pretty good. Might do this until I can save up for a whole cat back system. Are there any hp gains with just a muffler like this. If anyone has a link were you can here some good sound clips, that would be awesome. THANKS.

Catbacks as listed above give minal gains, like a few HP. If you want power get a Y-pipe and intake.

 

Get the cattman system. i have that and i love it. it's not to loud, not too soft. But do get and intake and y-pipe to accentuate your setup.
