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.
