Engineering Diablo E39 M5 X-pipe replaces the stock BMW resonator, between the
catalytic converter and the rear mufflers. Rogue has incorporated two, 12"
resonators in the X-pipe, to reduce cabin "drone."
E39 M5 X-Pipe Features:
The Rogue E39 M5 X-pipe is made to fit in place of the BMW factory resonator.
Other features include:
- Weighs only 18 lbs. for the entire assembly, including built-in
resonators. Factory resonator, with tubing, is over 27 lbs.
- 100% T-304 stainless steel construction and internals, many other
exhausts are made from 16 gauge stainless steel.
- Fully mandrel bent tubing, no crimps or flattened areas.
- Full TIG welded construction, no lock seams or pinch welds.
- Factory-like hangers for OEM fit.
- Optimized tubing sizes and minimized bends maintain exhaust velocity
without compromising necessary backpressure.
- Deep, throaty tone, without the drone.
- Can be used with other aftermarket mufflers including, but not limited
to the following brands:

- Will not change ground clearance
- Will not void factory warranty
- Will not affect emissions
All Stainless Steel is the same, right? WRONG!:
All Rogue Engineering Diablo exhausts are produced using only 100% full T-304
stainless steel because of its consistent strength characteristics, and
corrosion resistance. Recently, Rogue 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 subscribe to this practice in their production exhausts!
Rogue wants 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
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 almost all atmospheric conditions.
