Advice on which version Diablo to choose : -

The DIABLO (STANDARD) is your best choice if you ...
-Using your M3 as a weekend cruiser (top down, cruising) and just want a little bit of sound. Compliment it with our ROGUE ENGINEERING RASP pipe for buzz-free RPMs.
-Carry passengers in the car that are sensitive to louder sounds
-Would like to improve the look of the tips on the rear bumper with our popular 80mm, double wall, angle cut, staggered tips.
The Diablo CALIENTE is your best choice if you ...
-Want a more business-like appearance with our simple 80mm, single wall, straight cut, staggered tips.
-If you're running SUPERSPRINT STEPPED HEADERS WITH SPORT CATS and are looking for the most performance, the Diablo Caliente is better suited for your performance needs.
-If you want the deepest sound out of your S54 available

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 optimising tubing diameters to allow for adequate back pressure 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.

Rogue Engineering exhaust actually begins after the E46 M3 midpipe (aka Section 1). While others that produce an exhaust that starts just after the end of the exhaust manifolds and immediately merge the exhaust pipes into a "Y" pipe, we found in our testing that the exhaust gas velocity is severely hampered by this "traffic bottleneck". While you spend big money trying to select the best S54 header for your car, that decision is quickly extinguished as you immediately merge the exhaust pipe together immediately after the header itself. We found that even after the Section 1 that the exhaust gases velocity had slowed only a little, which made merging the exhaust pipe a better.

The first dyno graph is a comparison between a "street performance" exhaust (OEM Euro headers, stock section 1 and 2, aftermarket software, Eisenmann Race rear muffler) and a traditional 3" track exhaust on our E46 M3 test car. It makes some good power, but obviously, this is designed for a street car. The traditional 3" track exhaust replaces the "street performance" section 1, 2 and rear muffler removed and replaces it with a single tube exhaust, with a merge after the exhaust manifolds.

As you can see, there is an expected improvement in hp and torque from the single 3" exhaust after 5000rpm. Upon closer inspection, there is a DECREASE in hp and torque below 5000rpm. More importantly, there is an approximately 64 ft lb. LOSS of torque at the rear wheels at approximately 3400rpm. Some would argue that since this is a track specific exhaust that this acceptable since most of the time one would expect to be in the higher RPMs anyway (or hope to be). The reality is that if you're coming out of a corner at the track below 5000rpm, you're at a disadvantage.

The second dyno graph is a comparison between the aforementioned traditional single-pipe track exhaust and Rogue Engineering's Diablo TRACK exhaust.

Of course, the traditional track exhaust has shown a HP and torque improvement over street components (while sacrificing performance below 5000rpm). However, with Rogue Engineering's Diablo TRACK exhaust, not only do we see a slightly improve the top end performance, but we show a max torque differential of approximately 80 ft. lbs at 3400 compared to a traditional single-pipe track exhaust! Have your cake and eat it, too! This means having that all-so-important additional torque at the wheels coming out of corners while benefiting from the top end power on the straights!

The Rogue Engineering TRACK exhaust has been engineered to have two 90° bends in its 3" diameter tubing; one before the muffler and one directly after. These two bends proved to be a critical during the development as they added much needed backpressure to the system. Combine these with the custom-made, Rogue Engineering straight through muffler design and you have a free-flowing exhaust with enough backpressure to extract more HP without sacrificing torque!

Because of the modular design of the system, you can tune the sound of the exhaust to your needs.
Using catalytic converters in Section 1 before the exhaust (such as OEM Euro cats) will give you the quietest combination.
Using a RASP MID PIPE in Section 1, will give you a slightly toned down sound.
Using a straight pipe Section 1 (or removing the single resonator of the factory Section 1), will allow you to announce your arrival in your neighbourhood for miles around, as this will be the loudest combination.

Use of the system requires our "Y" connector pipe shown. This is the same "Y" connector found on our ROGUE ENGINEERING E46 M3 X-PIPE (VERSION 2), so for those that already have the X-Pipe, you do not need to purchase the "Y" connector.

Features:
- 100% T-304 stainless steel, mandrel bent and full TIG welded construction.
- Lightweight at just 35 lbs. (with Y connector), 43 lbs. lighter than the OEM Section 2 and OEM rear muffler.
- NOT compatible with vehicles that have installed a fuel cell in the trunk.
- Installation and Application Notes: While this is designed to be a track-specific product, this product may not meet (and does not claim to be) decibel restrictions at tracks with specific noise regulations.

Note :- these are sold EACH. For an E46, you need to purchased TWO to replace both of them on the car. For E9X M3 and E88 128i/135i, they only use ONE bracket. Each order includes a pair of replacement exhaust hangers at NO CHARGE!

The Rogue Engineering Exhaust Support Bracket replaces the steel OEM bracket 18-21-1-436-309 with a CNC'd 6061 ACQ machined replacement. Often times we see the original brackets on the vehicles they are rusty and bent. This allowed us an opportunity to create a lighter version while making it from a more corrosion resistant material.

The E9X M3 exhaust uses just one plate. It supports the two middle exhaust mounts.

There are two (2) exhaust support brackets under the E46. While one supports the rubber exhaust bushings (18-20-7-832-991) the other ones does not.

Features include;
-Weight savings (OEM is 745g while ours is 602g)
-Corrosion resistant, anodized aluminum (grey anodized, like our E46 M3 V-brace)
-Optional titanium hardware kit (Grade 5), anodized gold. Resists corrosion, saves weight.

NOTE: The price ALSO INCLUDES the optional 4 x Ti mounting bolts as pictured.

IF ordering more 2 or more sets we will refund you approximately £80.00 saving on the combined international shipping cost

Listed priced based on US Dollar rates at time of listing.

Fits the following;
1999-2006 E46 including 323, 325, 328, 330 and M3
2008-2012 E9X M3
2006-2013 E88 128 and 135i
