Supersprint products are developed around scientific knowledge. Supersprint designs and builds based on each engine's performance characteristics. Because it is actually easier to lose horsepower through misuse of larger diameter tubing and badly designed silencers, exhaust flow rates and velocity are dramatically increased by Supersprint designs while still retaining factory OEM diameter tubes. All design is validated by extensive testing which includes hours of dyno testing on Supersprint's exclusive in-house Maha 4-wheel chassis dynamometer. Supersprint headers are constructed completely of stainless steel ensuring you years of unmatched performance.
These Headers Fit:
2001-2005 BMW e46 325i, ci, ix Cabrio, Touring 2001-2005 BMW e46 330i, ci, ix Cabrio, Touring
