The Race Series muffler is meticulously designed for uncompromising performance, delivering an aggressive racecar-inspired sound.

This muffler stands as the ideal choice for dedicated racers, turbocharged engines, nitrous oxide fuel systems, or vehicles equipped with wild cam applications. It boasts a 2.25" inlet, a 24" overall length, and a 4" diameter round, angle-cut tip.

Kindly note that this muffler is of universal fit for rear exhaust and may necessitate welding or fabrication for installation, as it is not a direct bolt-on component for any specific vehicle.

Rogue Engineering Z4 M Diablo Exhaust

Rogue Engineering is proud to introduce their Z4 M Diablo exhaust. A cursory glance at the exhaust easily shows how this exhaust excels in both performance while saving weight. However, a closer look will show the pure artistry of its construction and elements of unique design.

Like the successful E46 M3 Diablo exhaust, the Z4 M Diablo exhaust is designed to compliment the high-revving engine concept which BMW has implemented into the M brand vehicles as of late. This means that the exhaust note will not only sound good at low RPMs, but also at the high RPM limit of the engine. Additionally, the Z4 M Diablo will improve performance at high RPMs with its straight-through muffler design.

Features:

  • Significant weight savings of 15 lbs. compared to the factory muffler
  • High-quality T-304 stainless steel construction for durability
  • Straight-through muffler design improves performance at high RPMs
  • Deep, throaty exhaust note complements the high-revving engine concept
  • Easy installation with factory-like hangers, no cutting or welding required

Installation of the Z4 M Diablo requires no cutting or welding as it requires the removal of the factory rear mufflers. Installation time is approximately 45 minutes. No new gaskets or hardware is required.

 The Supersprint 'Race' rear muffler system is one step beyond the standard Sport mufflers. Don't be fooled by the name - the 'Race' mufflers are designed for street use and the name only distinguishes it from the quieter standard Sport system. With the stock system the sound is very subdued. With the 'Race' mufflers the sound is much more noticeable and more aggressive - a perfect sound to compliment the assertive nature of an M Coupe or Roadster. You will hear this exhaust but it will not be intrusive or sound out of place on a civilized sports/GT car like the MZ4. The Supersprint center pipes to delete the rear resonators for more volume can be a welcome addition.
