Rogue Engineering E46 M3 Diablo Exhaust

Your Price: $1,395.00
Part Number:RE_DIABLO
In 2024, all E46 M3 Diablo exhausts will now change to straight cut, single wall, staggered, 80mm polished stainless tips.  We will no longer be offering the double wall, slash cut tips.

Rogue Engineering is proud of our E46 M3 El Diablo exhaust.  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. 

Over a Decade of Legendary Performance
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 our own facility, we felt we 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.

E46 M3 Diablo Features
The RE Diablo is made to fit exactly like factory.  Improved, updated specs!

  • Weighs only 30 lbs., 26 lbs. lighter than the factory muffler! (factory is 56 lbs.)
  • 100% T-304 stainless steel construction and internals
  • Fully mandrel bent, 57mm tubing, no crimps or flattened areas
  • Mil-finished pipes and muffler, 80mm double wall, angle cut tips.
  • 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.  Eliminate the factory RASP sound with the Rogue Engineering RASP Pipe!
  • Tuneable sound volume with the use of our EVC X-Pipe (Section 2)!
  • Easy to install (compared to other systems in the market)
  • Will not change ground clearance
  • Will not void factory warranty
  • Will not affect emissions
  • No permanent modifications required for installation

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.

The image above shows a stock exhaust, and the highlighted "chamber" which exhaust gases flow.  After these gases collect in the chamber, they exit through the exhaust tips.  This chambered collection area allow for backpressure to build, important for naturally aspirated vehicles at lower RPMs.  The problem with this design (and other exhausts designed with this feature), is that flow is ultimately impeded at higher RPMs.  This translates to adequate performance at the lower RPMs and compromised flow at higher RPMs. 

What makes the 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 the Diablo, we have met all of our design requirements.

Do you like apples?  How you like dem apples!
Equipped with optional equipment, your E46 M3 can see significant power gains with the the Diablo and Rasp Pipe.  Bolting on Rogue Engineering specific headers, intake, and software, combined with the Rogue Engineering Rasp Pipe and the Diablo exhaust, consistent power over stock was achieved without dips of hp or torque.  More gains would be expect if performed with 93 octane gasoline.  Of course, individual results will always vary.

Dyno runs performed with 91 octane.  Results are expected to higher with 93 octane.
