Rogue Engineering Diablo Exhaust (E46 ///M Cars)
Umnitza is proud to introduce Rogue Engineering's E46 M3 El Diablo exhaust. A close look will show the pure artistry of its construction and elements of unique design. Video 1, Start, Rev, Launch, Driveby (El Diablo with RE Rasp Pipe) [6.9MB] Hello? It's 2006. They already stopped production on the E46 M3. 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. El Diablo Features El Diablo Design 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. 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 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. Why not full titanium?

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!).
The RE El Diablo is made to fit exactly like factory. Features of El Diablo include:
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.
(Fully Burnt 'BLUE' titanium tips no longer available)
While full titanium exhausts have their merits, we decided against a full titanium unit for a number of reasons. Here are some of the pros/cons of the full titanium systems we've seen.

We decided to produce our system in 100% full T-304 stainless steel because of its consistent strength characteristics, corrosion resistance, and wide range of materials (important for controlling sound and exhaust flow). At 26 lbs. for our production system, we have reached the weight of some full titanium systems costing twice as much but with the benefits of using stainless steel. Do you like apples? How you like dem apples! If you are interested in similar gains on your E46 M3, please speak to a Rogue Engineering sales representative about the El Diablo Power Pack. Limited Production 12/20/06 After 6 months of continuous backorders, a limited number of El Diablo's are now in stock in our NJ warehouse. The perfect compliment to our El Diablo exhaust is our RASP Pipe.
Equipped with optional equipment, your E46 M3 can see significant power gains with the El Diablo and Rasp Pipe. Bolting on Rogue Engineering specific headers, intake, and software, combined with the Rogue Engineering Rasp Pipe and El 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 gas. Results are expected to be higher with 93 octane.

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