Supersprint Header/S-Pipe (BMW E46 M3) (view/hide)

19hp gain over factory BMW Euro system; stepped tubular headers/down pipe with S-pipe (no cats); bolts to the engine with factory hardware; clamps/slip-fit to Supersprint X-pipe or aftermarket equivalent.

Experience the latest design innovation from Supersprint for the E46 M3 and the new Z4 M -- 'stepped' design headers. While the technology has been in widespread use in Formula 1 for awhile, this is the first application of a stepped design on the E46 M3. In an engine that is tuned as much as the S54, airflow management is critical in getting big horsepower numbers from the exhaust. The Supersprint design is the next step in innovation in header design. By slightly increasing the size of the pipe diameters as the exhaust system moves away from the engine, the exhaust can flow more air. Supersprint's design is tuned specifically for the S54 engine which is important in making more power without losing low-end torque. The headers merge into a precision-fit merge collector and then exhaust gases flow into the oversized S-pipe. Our most-popular package is for the stepped headers with no cats (straight pipe) but cats are available for people who want to keep their cars somewhat streetable. Total horsepower gain with the complete system over a US M3 would be more than 30hp.
