The MagnaFlow E46 M3 Performance Exhaust System not only offers dyno-proven gains and superior fitment, but it makes your M3 sound exactly the way it should've from the factory.

Most owners feel that the E46 M3 doesn't exhibit an ideal exhaust sound from the factory, but the MagnaFlow exhaust system cures that problem with a moderately aggressive tone that is suitable for mild-mannered street cars driving around town, yet opens up nicely under wide-open throttle and will have you smiling all the way to the rev limiter. A sound that is deep and commanding at idle and cruising speeds to the all-out wail of the S54 at full throttle.

Significantly lighter than the factory exhaust, the MagnaFlow E46 M3 Exhaust System doesn't just look beautiful and sound great - it improves handling as well.

Each MagnaFlow exhaust system is designed to bolt right on and provide years of trouble-free performance with better-than-stock looks - and a lifetime warranty to back it all up.

  • Dyno-proven gains
  • Superior fit and finish
  • Neighborhood-friendly sound on the street
  • Full S54 wail at wide-open-throttle
  • Exceptional weight savings
  • Lifetime warranty
