WATCH: STRAIGHT PIPING MY WIFE'S E93 M3!


Adding an AFE Intake and gutting the muffler made the M3 faster and sound killer! 


Upgrading the M3's intake and exhaust were perfect modifications for Chelsey. The AFE Stage 2 intake added around +15HP and the butt dyno agrees. Once the exhaust was modified, the N/A V8 really came to life!
