I have a catless + non-resonated Fabspeed X-Pipe for sale. This will fit all e9x M3's. It will NOT trigger CEL's. According to Fabspeed's dyno its good for +15whp and +10tq. Was on my car for roughly a year and comes with the original clamps. Slightly louder at idle but floor it or blip the throttle and the car sounds down right mean. Regularly got compliments on the sound.
Asking $500 + shipping
Cash or Paypal accepted.

This does not include High Flow Cats. Its just the X-Pipe.
