A Do-It-Yourself exhaust install can be hard enough. But to stop in the middle of it to run to the dealer for gaskets, hangers, or special hardware is a major inconvenience. Don't be left taking the bus to the dealership on the hunt for parts. Get all of the parts you may need before the job begins! And with mileage we can almost gurantee that any section you remove will need to have new gaskets. Some of the gaskets are crushed to ensure a tight seal; other gaskets become stuck to their flanges. This set of hangers and gaskets for the 2001-2006 E46 M3 covers all of the sections of the exhaust, from the headers to the muffler.

The exhaust on the E46 M3 is broken up into sections -
headers - gaskets at the cylinder head and at the outlet to section 1, plus an air pump gasket
section 1 - crush gasket rings on the inlet and flange gaskets at the outlet to section 2
section 2 - flange gaskets at the inlet and steel exhaust rings at the outlet to the muffler
muffler - steel exhaust rings on the inlet with special square-shouldered nuts (included with hanger/gasket kit)

This package also includes 3 new muffler hangers and the 2 hangers in the center of the exhaust (mounted on section 1).

We also offer most of the exhaust hardware you may need -
Torx bolts and nuts for the header-section 1 connection
copper nuts for the section 1-section 2 connection (M8x30 bolts can be re-used)

Applications:
2001-2006 E46 M3 coupe, convertible

Rogue Engineering is proud to introduce 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. El Diablo Features The RE El 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 tubing, no crimps or flattened areas Mil-finished pipes and muffler, mirror polished stainless steel quad 80mm Club Sport 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.

Special Pricing! These Supersprint 'partial-stepped' headers for the Euro E46 M3, MZ3, and Z4 M are a replacement for the stock manifolds/cats. These are the tubular 'stepped' equal length headers (not the full racing stepped headers) - the header pipes increase in diameter the further they get from the engine until terminiating in a stock Euro-type flange. These stepped headers will bolt to the stock section 1 of the Euro exhaust. For making E46 M3 horsepower and performance gains, headers are right at the top of the list (along with changing the rear end gears). Since the stock catalytic converters are in the original exhaust manifolds, using any type of tubular non-cat manifolds will give instant power gains. The Supersprint headers are full 304 stainless steel (not mild steel) for better heat dissipation and heat resistance to cracking and de-forming (any headers not made from stainless suffer from structural problems). Supersprint designs their headers with CAD programs and 50 years of exhaust tuning experience. These headers are an improvement over any 'Euro style' header on the market. This part is designed for the Euro market with the correct flanges for the Euro exhaust and the O2 and EGT sensor ports pre-installed. Special software or stand alone engine management would be required to keep check engine and fault codes from appearing. Software is recommended to maximize the performance gains from this header upgrade.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust design because every aspect is done to such a high level. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

Section 1 / Catalytic Converter Options
This header works with the flanges on the Euro section 1 (clocked differently than the US exhaust). It only works with the stock Euro section 1 or similar.

Replaces the factory section 2 mid pipe. ​Like all RE products, the section 2 x-pipe was designed to be both high quality as well as functional. Whereas the factory section 2 utilizes two 60mm diameter tubes, with a "H" crossover and small resonator, the RE X-pipe maximizes gas velocity by merging the two smaller tubes into one larger 76mm tube before splitting back into two before the rear muffler. This efficient system allows for gas velocity to equalize from cylinders 1-3 and 4-6, before entering the muffler chamber, improving sound as well as gas velocity. As an added feature, the incorporated external "dump" at the end of the X-pipe for total user controllable sound. The optional EVC valve allows the user to control the exhaust sound from stock (completely closed) to race-like loud (completely open) from within the inside of the vehicle. The user has the option of any variable position (partially open), controlling the exhaust volume and flow. It takes less than 3 seconds to fully open to fully closed. The RE X-Pipe is made to fit exactly like factory. Features include: Weighs only 12 lbs. with included blockoff plate (factory is 22 lbs.) Optional Electronic Valve Control (EVC) valve allows for user controlled exhaust sound levels with touch of a switch (designed to be mounted inside the cabin, with a discreet momentary switch) 100% T-304 stainless steel, full TIG welded construction. Version 2 now incorporates a 2-piece design allow for integration of the ROGUE ENGINEERING E46 M3 TRACK EXHAUST Includes all hardware require to mount to aftermarket exhausts. Will not change ground clearance Will not affect emissions No permanent modifications required for installation EVC Kit - ES3509316 The optional EVC sound control kit includes the following: US-made EVC Valve (6061-T6 Aluminum body and plate, stainless steel butterfly/shaft, High Temp Steel Gears) Custom wiring harness, specifically designed for internal console mounting in E46 M3. All you need is power and ground source for wiring. Custom momentary rocker switch Hardware and gaskets for mounting valve to RE X-Pipe.
