Rogue Engineering E46 M3 Diablo Exhaust

The Devil's in the Details!

The Rogue Engineering Diablo E46 M3 is a slick piece of exhaust engineering. Rogue had a difficult task in creating a high flow exhaust system while incorporating the bends and curves of this particular section 3 location. The stock section 3 exhaust is considerably restricted for a number of reasons. Rogue addressed these issues with an artistic take on exhaust manufacturing. The system incorporates dual 50mm T-304 stainless steel tubing for ideal back pressure and flow. The system mandrel bends into a straight through, composite resin packed silencer and directs the gases through 4 80mm polished stainless steel tips (burnt titanium available). This system reduces exhaust gas restrictions to practically zero for a noticeable boost in horsepower and torque while dampening the exhaust sound into a throaty, deep tone that lacks the highway "drone" of some other performance exhausts. 

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

• Weighs only 26 lbs., 1/2 the weight of the factory muffler! (factory is 56 lbs.)
• 100% T-304 stainless steel construction, internals
• Fully mandrel bent tubing, no crimps or flattened areas
• Mil-finished pipes and muffler, mirror polished stainless steel quad 80mm angle cut, staggered tips.
• Full TIG welded construction, no lock seams or pinch welds.
• Rogue Engineering logo tastefully stamped in the body of the muffler
• Optional 80mm Titanium tips
• 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.
• Will not change ground clearance
• Will not void factory warranty
• Will not affect emissions
• No permanent modifications required for installation

Diablo Design
The stock exhaust uses a "chamber" into which exhaust gases flow. After these gases collect in the chamber, they exit through the exhaust tips. This chambered collection area allows for backpressure to build, important for naturally aspirated vehicles. 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 Rogue Engineering 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 large, 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 RE Diablo, we have met all of our design requirements.

Limited Production
Because of the complexity of the manufacturing of the RE Diablo, availability will be somewhat limited. Please check availability with us to determine our current inventory level.

Dyno Proven Results

The Rogue Diablo Section 3 has become apart of a power recipe we have made here at BimmerWorld. The recipe consists of 4 main ingredients- aFe Intake, Shark Injector, proper tuned header, and Rogue's full header-back system. These key ingredients produce an extra 30hp at the wheels! This is a considerable amount considering the level of design and engineering of the original components and the fact that the S54 is already making 104hp per liter! With our power recipe, keeping up with a E9X M3 isn't a problem!
