Videos of the Rogue Diablo Exhaust:

Rogue Engineering is proud to introduce their E60 M5 DIABLO exhaust. A cursory glance at the exhaust easily shows how this exhaust excels in performance while saving weight. However, a closer look will show the pure artistry of its construction and elements of unique design.

Sound Tailor Fit For YOU!
The Rogue Engineering E60 M5 Diablo is more than just a great sounding exhaust. By studying the factory exhaust system, it just made sense to develop the exhaust the way Rogue did.  The Diablo system replaces the rear mufflers (shown in orange) only, while leaving all other sections in place.  If you're looking for more sound, you can replace the center crossover resonator (shown in green), with Rogue Engineering's E60 X-Pipe replacement.

The factory system uses catalytic converters and resonators in the system to help control sound and emissions. Simply removing these items from the system would theoretically add power, but also add unwanted noise levels. Other companies that offer "full" exhaust solutions (complete front to back) like to make these infinitesimal power increases but really are trying to justify the added cost and tooling of the extra tubing and welding required to produce this "system". When you weigh the benefits, it just did not make sense to Rogue ton develop a full replacement system.

After studying the benefits of a muffler-only replacement, Rogue worked on the sound. Internal muffler tuning done the old fashioned way, tweaking the dimensions of the muffler, the internal perforated tubing (perforation size, spacing, and tubing length) are all factored in to get the exact desired sound which makes it unmistakably a Rogue Engineering DIABLO exhaust for the E60 M5. Since this muffler design is a straight-through design, the performance gain from the decrease in restriction is an expected benefit as well.

E60 M5 Diablo Features:
The RE E60 M5 Diablo is made to fit exactly like factory. Features of E60 M5 Diablo include:

• New design now weighs only 17.4 lbs. per side (stock is 38 lbs. per side). Saves 41.2 lbs.!
• 100% T-304 stainless steel construction and internals, many other exhausts on the market are made from 16 gauge stainless steel.
• Fully mandrel bent tubing, no crimps or flattened areas
• Mil-finished pipes and muffler, mirror polished, Rogue Club Sport double walled, stainless steel quad 89mm, staggered tips. Completely fills in factory valence without modifications.
• Full TIG welded construction, no lock seams or pinch welds.
• Factory-like hangers for OEM fit.
• 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.
• Will not change ground clearance.
• Will not void factory warranty.
• Will not affect emissions.
• No permanent modifications required for installation.

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.
