Supersprint has being offering a full exhaust, from-turbo back, for the limited-production 2011-2012 BMW 1M Coupè E82, since day one.
Our goal for the 1M was more power, better sound, less weight.
Starting out at front, our turbo downpipes eliminate the massive, power robbing restriction of the stock, primary cats.

Contrary to the populer belief, designing downpipes for the N54 powerplant the proper way is not an easy task.
The small space available within the engine bay, and the critical placement of the turbo chargers, leave little or no room for smooth-bend downpipes.
Regardless, the Supersprint R&D Team made things right, designing a set of unique downpipes, built with tight-radius, 90° stamped-halve collectors.
This proprietary, outstanding feature guarantees the path of least resistence for the exhaust gas escaping from each of the turbochargers' outlet ports, yet it ensures a perfect fitment within the narrow engine confines.
We at Supersprint are extremely proud of our own design, as the alternative downpipes available on the market today are either made with cheap, wide radius, sharp angled collectors (not as efficient in terms of gas flow, and bad for performance), or built with thicker, heavier cast steel collectors.
Another exclusive, functional feature of the Supersprint Downpipes is the floating, expanding pipe joints, designed to relieve all of the thermal induced tensions off of the initial exhaust tract.
This section is the most critical, mechanically stressed area of the entire exhaust system.
The Supersprint Downpipes guarantee not only the best performance, but also the longest life.
Moving downstream on the exhaust, our front pipes use a set of HJS Motorsport, high flowing, twin metallic cats, a drone-killing mid resonator (also available in a straight pipe version) and a specific rear muffler.
The Supersprint, free-flowing Race rear muffler enhances the sound of the N54T Twin Turbo engine to the perfect tune.
Thanks to thin-walled, high grade stainless steel, and to the no-frills, race inspired overall design, the Supersprint full exhaust is lighter than stock; the saving varies, depending on each specific configuration among the available options.
As usual, the installation is easy, straightforward, requiring no modifications.
Now that the BMW 1M Coupè has become a contemporary classic Sportcar, the time has come to change to the Supersprint exhaust, making the car more valuable yet.
