15 exhaust setups for the E9X M3
Complete list of the most popular exhausts for the S65 V8 E9X M3! So you’re looking to make your E90 M3, E92 M3 or your E93 M3 louder and faster, well this may be a good place to start. Exhausts can add so much to your driving experience from the vibrations in the car to the gained horsepower. Here’s a few exhausts that are super popular on the E9X M3!
With the racetrack and the street in mind, this new exhaust was designed using an extremely heat-resistant and lightweight chrome-nickel alloy called Inconel®. This optimized exhaust conduit allows the M3’s V8 engine to breathe more easily (reduction in backpressure) and create a very powerful sound.
- Powerful and sporty exhaust note with no droning for everyday suitability.
- Fabricated from a chrome-nickel alloy called Inconel®. Inconel® is an extremely heat-resistant and strong material. These qualities allowed engineers to reduce the wall thickness of the exhaust from 1.5mm to 0.8mm without sacrificing strength. This resulted in a weight reduction of approximately 40% (~20 lbs.) when compared to the stock exhaust. Inconel is very corrosion resistant and has been used at the highest level of Motorsports.
- Perforated inner pipes and polished titanium tips (laser-engraved with the M logo) represent the ultimate in technology and sportiness, accentuating the individual character of the BMW M3.
- Developed using state-of-the art CAD and FEM technology, ensuring optimum fit and OEM quality.
Welcome to Version 2 of the Valvetronic Designs E9x M3 exhaust system. Version 2 brings on new improvements that push us past the competition. First is a return to Vacuum valves. These valves have proven to be far more reliable than electronic ones. We have also improved the sound quality to give a more pure driving experience to make this system the best on the market for the E9x platform. These systems are fully mandrel bent for maximum flow and are constructed out of T304 stainless steel, the highest quality material on the market. Our dream is to offer the BMW community an incredible valved exhaust without charging the dreaded “M tax” and that dream has come true. For far too long these systems have been out of reach for most people, but no longer. This system comes with everything you need to have your E9x M3 sound like a beast on your favorite backroad, or cruise to the shops without alerting the authorities. Your time to take control of your E9X M3 sound is now.
You now have the option to pair your Valved rear section with the best sounding mid pipe all in one place.
*FORWARD X-PIPE (TRADITIONAL V2): This midpipe is quite different than most, featuring a freeflow x merge right after the transmission tunnel. This design helps allow for maximum exhaust scavenging and power gains throughout the rev range. At the rear of the midpipe we have two 12-inch resonators to smooth the exhaust sound and provide noise mitigation. We also offer a catted version of the X-pipe for those who do not want to go fully free flow. This X pipe is designed for those who want maximum sound and maximum Horsepower gains, it is not for the weak of heart.
*Central X-pipe (OEM X-pipe) (LIMITED EDITION): Our central X mid pipe moves the x back to the factory location and puts the resonators in front of the X pipe to properly smooth exhaust tones before the merge point. These developments culminate in a very enjoyable deep sound experience with a slightly more exotic flare up top compared to the V2.
Sound tones are very similar in each setup due to the same resonators being used. You can not go wrong with either setup!
Looking to increase your total horsepower, torque, and significantly beef up your sound? American Racing Headers is a group dedicated to providing the best all around headers and exhaust money can buy! 100% Made in the USA of high quality 304 stainless steel and using 3/8″ thick laser cut flanges for a warp free seal, you can trust that your exhaust components will be built to the highest specifications and will more than likely outlast the rest of your car.
To ensure high power output and the best sound possible, the 304 stainless steel tubing is routed in a specific way to optimize flow through the headers. Using primary tubes that measure in at 1-3/4″ diameter each, these are built to specific lengths so that exhaust gases are directed in way that makes them flow highly efficiently and prevents any sort of restriction that would otherwise limit your engine’s total output. The gas exits the engine’s head then flows down the system, in time, to the 4-to-1 Merge Collectors. These Merge Collectors direct the gases by taking advantage of the natural firing exhaust pulses to create an effect that scavenges the exhaust from the primaries and keeps the exhaust gases moving at their optimum speed. This means more flow and more power at every point of the throttle band all the way up past redline.
For a slightly lower flowing header system that also includes all needed exhaust components, check out ES3426888 which features 1 5/8″ exhaust primary tubes.
The header system attaches to an x-pipe with incorporated 200-cell metallic substrate catalytic converters for extreme durability and to prevent check engine lights in the long run. These are performance catalytic converters that prevent any restriction in your system while still functioning as needed.
Next in line are a pair of resonators to allow the exhaust gases to momentarily collect and expand, helping keep the exhaust flow as smooth as possible and remove some excess noise. If you would like a system without resonators to help add a little more aggression to your exhaust, check out ES3426896 with de-resonated mid-pipes!
Finally are a pair of high performance mufflers. These keep you street legal while still producing a beastly roar, especially under heavy acceleration! Each muffler gives off a deep satisfying growl through their twin polished stainless exhaust tips.
This full exhaust system includes all brackets/hardware needed for assembly and mounts to stock mounting points using the typical rubber exhaust hangers.

To get the most power out of a stock or modified vehicle, it is necessary for the exhaust to flow cleanly and unrestricted. However, a stock exhaust and muffler system can significantly reduce the flow of your exhaust system. Stock exhausts are perfect for daily driving, as they keep your exhaust quiet and local law enforcement out of your rearview mirror. But if you take it to the track, that stock exhaust can really put a damper on the time of your passes.
Upgrade your exhaust system while adhering to local laws with this system from AFE. The kit installs easily, using all of the stock mounting locations of your factory exhaust system but will give a more free flowing, higher performance sound. With exhaust gases leaving faster, more air can be drawn in, and better throttle response and horsepower can be expected.
