Cats out =
- stank exhaust smell
- no hp gain unless you're also changing out the mufflers
- check engine light
- O2 sensor warning
- failed emissions
Even if you went to tubed headers, CAI, straight pipes and race mufflers...you wouldn't get 20 hp. BMW engines just don't do that, they are already built at the top of their game. Changing out the exhaust on a M3 wouldn't yield that, let alone a X5.
