▀▄ eas - Rogue Engineering - El Diablo Exhaust for E60 M5

Gentlemen,

Rogue Engineering has a E60 M5 exhaust on the market that I wanted to make you guys aware of. Hear and feel the incredibly deep tone that retains the unmistakable V10 wail at high RPMs with the Rogue Engineering E60 M5 DIABLO exhaust. After nearly a year of development, we're ready to release the beast into the marketplace! 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.

Just Mufflers? Where's the rest?
The Rogue Engineering E60 M5 Diablo is more than just great sounding exhaust. By studying the factory exhaust system, it just made sense to develop the exhaust the way we did.



The factory system uses catalytic converters and resonator 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 us when developing a full replacement system.

Pros and Cons of "Full" Exhaust System Solutions

Pros:
- Lighter than stock
- Slight power increase
- No cutting required

Cons:
- Increased cost, typically 2x or 3x the cost of just mufflers
- Drone in cabin from lack of resonators
- Exhaust volume may be too much, and cannot be controlled
- No longer meets emissions without cats
- Fit may be an issue, with much more factory parts being replaced

After studying the benefits of a muffler-only replacement, we 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 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:

- Weighs only 21 lbs. per side (stock is 38 lbs. per side). Saves 34 lbs!
- 100% T-304 stainless steel construction and internals, a majority of the exhaust made from 16 gauge stainless steel
- Fully mandrel bent tubing, no crimps or flattened areas
- Mil-finished pipes and muffler, mirror polished stainless steel quad 89mm straight cut, 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
