The factory header system on the M5/M6 V10 is nicely designed - except where the primary tubes join together. Here the factory tubes are crushed in size and joined in narrow housing ahead of the catalytic converters. Supersprint has designed a fully tubular header and collector system that is fully mandrel bent and makes no compromises. They even patented the design. With a complete exhaust system, we recorded gains of over 60hp! These headers can be connected to either a factory secondary cat or a Supersprint high-flow metallic cat.

What sets these headers apart from others is the expertise and craftsmanship from Supersprint in Italy. These are 100% stainless steel headers with true mandrel bends. It's a carefully engineered header and merge collector design with superior craftsmanship to other systems (sometimes knockoffs to the original Supersprint). Supersprint spends considerable time in R&D, experimenting with piping sizes and layouts to get the most horsepower gain (confirmed with their in-house dyno). Fitment is also a key consideration and this is where Supersprint's commitment to quality fabrication and construction set them apart from cheaper systems.
