The Rogue Engineering E85 MZ4 X-pipe replaces the stock BMW resonator between the catalytic converter and the rear mufflers.

The RE E85 MZ4 X-pipe is made to fit in the place of the factory resonator. Features include:

• Fits all MZ4 Coupe/Convertible from 2006-08
• Weighs only 11.35 lbs. for the entire assembly. The factory part is over 15 lbs.
• 100% T-304 stainless steel construction and internals, a majority of the exhaust made from 16 gauge stainless steel.
• Fully mandrel bent tubing, no crimps or flattened areas
• Mil-finished.
• Full TIG welded construction, no lock seams or pinch welds.
• Factory-like hangers for OEM fit. Fits with factory or aftermarket mufflers (that use flanges).
• Optimized tubing sizes and minimized bends maintain exhaust velocity without compromising necessary backpressure
• Deep, throaty tone, without the drone.
• Will not change ground clearance
• Will not void factory warranty
• Will not affect emissions

Match this with the Rogue Engineering E85 Mz4 Diablo Exhaust! ES3546835.
