Rogue
Engineering E39 M5 X-Pipe
2/1/09: In
stock!
The Rogue Engineering E39 M5 X-pipe
replaces the stock BMW resonator, between the catalytic converter
and the rear mufflers. We have incorporated two,
12" resonators in the X-pipe, to reduce cabin
"drone".

E39 M5 X-pipe Features
The RE E39 M5 X-pipe is made to fit in the place of the 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, 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
- 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 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.
Installation Notes
 We
have excellent success using the KD Tools 2031 exhaust cutter for
the installation of this exhaust. It cuts straight, without a
saw blade, and leaves a clean, chamfered edge. At less than
$30, a worthwhile purchase available from SJ
Discount Tools.
