DMS E46 Exhausts (325/330)
October 2003 - Our latest production of E36 and E46 DMS exhausts now incorporated a new core center, reducing total exhaust volume slightly more, without impeding flow. Additionally, for those with aftermarket E46 bodykits, we have also narrowed the overall tip width by bringing them 3/16" closer together.
Rogue Engineering is proud to introduce its latest performance product, the DMS exhaust system. 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.
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 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 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.
