There are a lot of E90 M3 / E92 M3 test pipes, center pipes, mid-sections on the market but this has to be the best one. Test Pipes require you to cut your stock exhaust and still leaves secondary catalytic converters. Other mid-pipes or center sections don't have an x-pipe or have it placed too far away to have much benefit. After a lot of R&D and testing, including racing with multiple designs, we now have the E9X M3 center pipes to trump them all.

The key to our center section is the X-pipe placed as far forward as possible. An X-Pipe has been proven to increase torque and horsepower, especially in the upper RPM ranges. The X-Pipe design relies on exhaust velocity to be the most effective so it must be located as close to the engine as possible. We placed it where both banks merge, an ideal location. The front half of our exhaust works just like any Test Pipe set on the market, eliminating the primary cats. The rear half of our system eliminates the secondary cats and is available as straight pipes for maximum flow (or optionally with resonators to tone down the exhaust note - See BimmerWorld part # 1004330 for resonated version). Made in the USA from 304 stainless steel.

Epic Motorsports tuning is very strongly recommended with this exhaust. Exhaust flow is significantly changed with this design and special tuning may be desired to restore low-end torque and take full advantage of the increased flow. Other tuning software - even Race tunes - may not take this change into account.

These are designed for race or track use only. They bolt to the stock S65 headers with factory gaskets and any rear exhaust muffler system can be used. This allows you to remove and store your stock catalytic converter/mid-section without having to cut it up. If you need to go back to stock in the future, simply swap center sections and continue.
