what model?? and maybe then i can steer you in the right direction. almost every vehicle on the road can have a upgraded exhaust to get better performance.

i've got a 05 mazda6 3.0L..... what exhaust would be best for performance wise? do you know the stats?

Theres no exhaust on the market that show any kind of gains for the mazda 6. The stock cat back is just about as efficient as you can get. The restrictions are all pre-cat. People only buy exhausts for sound/look on Mazda 6s.
