Premium-quality, lightweight stainless steel exhaust system for maximized performance and sound quality

The MagnaFlow Performance Exhaust System for your F8X M3/M4 not only offers dyno-proven gains and superior fitment, but it makes your M3 sound exactly the way it should've from the factory.

The F8X M3s and M4s sound nice from the factory, but they're designed to have a more subtle tone for the average BMW owner, so there's only a hint of the performance available under the hood. MagnaFlow exhaust systems cure that problem with wide-open performance mufflers that offer a moderately aggressive soundtrack. The smooth, deep tone is suitable for mild-mannered street cars driving around town, yet it opens up nicely under wide-open throttle to have you smiling all the way to the rev limiter.

MagnaFlow Performance Exhaust Systems are constructed of 100% polished stainless steel. The mufflers are lap-joint welded for solid construction and rugged reliability even in the most extreme conditions, and they feature a free-flowing, straight-through perforated stainless steel core, stainless steel mesh wrap, and acoustical fiber fill to deliver the performance and sound you're looking for.

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

With the full MagnaFlow system weighing in at approximately 50 lbs, it's significantly lighter than the factory exhaust, so the MagnaFlow Performance Exhaust System doesn't just look beautiful and sound great - it improves handling as well.

The F8X M3/M4 Performance Exhaust System is available with your choice of sound characteristics:

Touring - a smooth, deep, moderately aggressive tone that is suitable for street cars from mild to not so mild

Sport - more aggressive, louder exhaust, especially when you are wide-open on throttle.

Both systems accommodate factory valves for improved sound shaping, and both are also available \ with a ceramic coating in either Titanium or Black finish for a refined and modern look.


  • Dyno-proven gains
  • Superior fit and finish (Titanium or Black)
  • Touring or Sport models for sound choice
  • Neighborhood-friendly sound on the street
  • Full German soundtrack at wide-open-throttle
  • Exceptional weight savings
