Rogue Engineering E36 DMS Exhausts
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 dual
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 faster flow.
Since 2001, we have continued to keep the
unique look and sound of the DMS a well kept secret among BMW enthusiasts far
and wide. It's no wonder other competitors continue to try to replicate
the success of the DMS with their Version 3, Gen 2 and many other versions as
they desperately try to copy the unique features of our exhaust. Make no
mistake, there is only one DMS exhaust. Available only from Rogue
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
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 made.
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 made from T-304 stainless steel, internal perforated tubing, muffler tips,
and muffler shells. The entire exhaust system is TIG welded 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.
You will also notice small details such as the
placement of the exhaust tips on the muffler bodies. The mufflers have
been specially designed so that the tips do not have to make strange, obscure 45
degree bends to fit through the rear valance. This is because the mufflers
were designed for a BMW, not a generic muffler part number with
tips and tubing welded onto them.
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).
