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
- 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.

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
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.
