When deciding on the right exhaust the hardest part is feeling confident in the best sound mixed with increased performance, this really leaves you to guess based on reputation. Fortunately, Supersprint has the reputation covered when it comes to BMW exhausts. For over 60 years their goal has always been designing and building the highest quality exhaust available. This has been achieved through extensive testing using real race teams to get the best feedback there is to offer, from the ones who demand the best everyday. Extensive dyno testing, high quality materials, and race team feedback are what allow Supersprint to extract the power from your engine, not just the noise.
Experience the latest design innovation from Supersprint for the E46 M3 -- '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 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. After the headers, the stepped piping size continues into the Supersprint section 1 with or without cats. The section 1 must be purchased separately. Any section 2 and rear muffler can be used with the Supersprint section 1. Our most-popular package for track cars is for the stepped headers with no cats (straight pipe) but cats are available for people who want to keep emissions in check (or if your rules require them). Total horsepower gain with the complete system over a US M3 would be more than 30 hp.
- 15-19 hp gain over 'Euro-style' headers
- full stepped tubular and equal length headers
- bolts to the engine with factory hardware and gaskets
- used with Supersprint stepped section 1 (with or without cats)
