Rogue - El Diablo Performance Exhaust - BMW E46 M3

Rogue Engineering is proud to introduce the E46 M3 El Diablo exhaust with 80mm Double Wall Club Sport tips. A cursory glance at the exhaust easily shows how this exhaust excels in both performance while saving weight. However, a closer look will show the pure artistry of its construction and elements of unique design. It's not like Rogue Engineering to rest on its laurels when it comes to development of any performance product. In fact, we are typically the first to market of product in many instances. However, when it came to the E46 M3 exhaust, we were definitely NOT the first ones on the block. By last count, there were already over 20 different companies offering exhausts for the E46 M3. Some companies even offer multiple selections (as if they couldn't make up their mind which was best!). After listening and installing countless aftermarket exhausts in their own facility, RE felt they had heard and seen enough of the good, bad and very cheezy. We recognized that most E46 M3 owners had very specific requirements to meet that they found in other exhausts out there. What you see here is the culmination is the best features of many of the exhaust systems found today, at an affordable price with the performance you come to expect from a Rogue Engineering product. El Diablo Design; Daring to be Different Much development was spent to optimize the El Diablo exhaust system. To understand the improvements, it is important to see how a stock exhaust functions. What makes El Diablo different is that it is a true "flow through" exhaust system. There are no design elements to slow down the exhaust gases when they speed up with higher RPMs. Part of the challenge of this design is optimizing tubing diameters to allow for adequate backpressure while preventing faster exhaust flow from being blocked or slowed. If you build a system with tubing diameters that are too larger, it results in an exhaust with poor street performance. Tubing diameters that are too small will restrict higher RPMs. The key is a balance, all while producing an exhaust that has a nice deep, mellow tone (a function of muffler size, perforated tubing size, and perforation size). With El Diablo, we have met all of our design requirements. Features: - Weighs only 26 lbs., 1/2 the weight of the factory muffler! (factory is 56 lbs.) - 100% T-304 stainless steel construction and internals - Quad 80mm double wall club sport tips - Fully mandrel bent tubing, no crimps or flattened areas - Full TIG welded construction, no lock seams or pinch welds - Rogue Engineering logo tastefully stamped in the body of the muffler - Flow-through design does not create muffler hot spots found on chambered mufflers - Optimized tubing sizes and minimized bends maintain exhaust velocity without compromising necessary backpressure - Deep, throaty tone, without the drone. Virtually silent at idle, but appropriate tone at higher RPMs - No permanent modifications required for installation Models Supported 2001-2006 BMW E46 M3
