exhaust does not fit non-US models.
Rogue Engineering introduced the DMS exhaust system in 2001, the first of its
kind in the BMW aftermarket. The DMS (Dual Muffler System) exhaust system
represents the latest in performance aftermarket exhaust technology, yet to be
uncovered in the BMW marketplace. With its design inspired by the awesome
McLaren F1, the DMS mufflers are tuned specifically for each car so that the
desired balance of power, torque, and sound are achieved.
Why in the world would we completely design an E36 exhaust from scratch? To
prove that there is always a way to create a better mousetrap. The Rogue
Engineering DMS (Dual Muffler System) exhaust system represents exhaust
development brought to epic levels never before seen or done before in
performance exhaust development.
The DMS system is more than a unique looking muffler system. Its twin
mufflers allow each bank of exhaust gases coming from the factory catalytic
converter to remain separated as they exit the exhaust. Whereas most aftermarket
exhausts use just one muffler, allowing for gases to pass between each of the
internal pipes, the DMS system maintains the exhaust gas velocity coming from
the cats by keeping them separate. Faster exiting exhaust gases equates to
Extensive Research & Development
When we begin our research for a performance exhaust system, we have to analyze
each and every aspect of the system. With factors such as tubing size, shape,
diameter, internal muffler baffling and more, how do you know when you've got
the correct balance?
Automobile manufacturers have a tough job, designing an exhaust to meet the
varying dB limits set all over the world. Fortunately, for most aftermarket
companies, they can be louder than stock (which is what most enthusiasts want
anyhow), without any regard for the end result. Whereas some aftermarket exhaust
manufactures will normally weld tips onto a pre-existing muffler, run some inlet
tubing, they may have enough time that day to even catch lunch on time. Most all
aftermarket exhaust systems will make more power than stock simply because of
the free-flow design of the muffler. However, have they optimized and analyzed
the best combination between power, torque and sound? Our research has shown
that they have not.
By testing various configurations of tubing size, muffler size, and custom
muffler internals, we are able to develop a system with a unique look, realistic
power gains, with sound control (idle, full throttle, and highway cruising).

What's in a "Stainless Steel" Exhaust?
With so many exhaust manufacturers out there, how can one be different from the
other? It's all about the internals.
Ask most exhaust companies what they use inside their mufflers, and chances
are, they don't know. They may say things like "confidential
information" (in other words, they don't know), "sound absorbing
packing", or even "high temperature, stainless steel wool".
Frankly, since many companies do not have control over their own production,
have no idea who makes their product (or if they even speak English!), and have
never seen the internals of their own product, so they can't tell you how it's
Is the exhaust(s) TIG welded? MIG welded? How do they control sound? Baffle
system? Perforated tubing? What prevents the internals from "blowing
out" over time? Although these question may not interest the average
person, the typical Rogue Engineering customer is itching to know.
The Details of the Rogue Engineering Exhaust
Rogue Engineering's exhaust systems are proudly built in North America, using
T-304 stainless steel tubing, internal perforated tubing, muffler tips, and
muffler shells. The entire exhaust system is TIG welded where possible (nearly
everywhere) for smooth, small, even welds. Our near seamless welds do not have
the "splatter" found on some MIG welded products. After welding, the
mufflers and tips are polished to a near mirror finish.
Longevity was a priority for the Rogue exhaust system. Therefore, rather than
simply packing the internals of the muffler "who know's what", the
perforated tubing is tightly wound with stainless steel wool. This prevents the
ceramic-thermal blanket used in the Rogue exhaust to prematurely "blow
out", a common problem with inferior quality systems. Whereas no system can
last forever, it's details such as these that allow the exhaust system to
maintain a consistent performer the moment you bolt it on your vehicle.
Unique Sound and Power
How does it sound? Civilized sound with an aggressive tone when prompted.
Virtually imperceptible droning at highway speeds and stock like idle when
sneaking into the neighborhood late at night. Deep throaty sound when the revs
increase, without the typical "Asian Import" sound at higher RPMs
found in exhausts produced overseas (Hmmm...there may be a correlation).
