Rogue Engineering MZ4 X-Pipe

Rogue Engineering MZ4 X-Pipe

Your Price: $595.00
Part Number:RE.MZ4.XPIPE

The Rogue Engineering E85 MZ4 X-pipe replaces the stock BMW resonator (shown in green below), between the catalytic converter and the rear mufflers.   A perfect compliment to our MZ4 Midpipe and MZ4 Diablo exhaust system.  

 

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

  • Fits all MZ4 Coupe/Convertible from 2006-08
  • Weighs only 11.35 lbs. for the entire assembly.  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!

All Stainless Steel is the same, right?  WRONG!
All Rogue Engineering Diablo exhaust are produced using only 100% full T-304 stainless steel because of its consistent strength characteristics, corrosion resistance, and wide range of materials (important for controlling sound and exhaust flow).  Recently, we examined a well known exhaust brand only to discover the use of 20 gauge stainless steel (stainless is typically sold by weight) throughout the muffler body.  While great for reducing weight, this is not a good practice when trying to build a product to last.  This common practice of weight (and cost) savings occurs in European and US made exhausts.  Rogue Engineering does not prescribe to this practice in their production exhausts!  We want you to enjoy the exhausts for many years to come, even if it means sacrificing some weight savings (all Rogue Engineering exhausts are lighter than stock units).

Beware of some companies that pre-coat their exhaust products with "thermal coatings".  In fact, they may be hiding inferior stainless steel or inferior welding processes.  Rogue Engineering Diablo exhausts are always TIG welded and never coated.

Some companies have chosen to build their "stainless steel" exhausts with Grade 409 stainless, because it is less expensive than 304.  While Grade 409 will resist atmospheric and exhaust gas corrosion, a light surface rust will form is most all atmospheres.
