This is Supersprint's best Bolt-On header for the E46 M3 & M-Z!...

Supersprint's patented design is quite unique in that it offers a smaller high-velocity diameter primary at the engines exhaust port and later increases to a greater diameter at a specific distance from the cylinder head. The result from the larger tube is maximum horsepower at high RPM, while the small tube maximizes low-end torque. Its is the combination "stepped" construction that makes the one of the best headers on the market, and worth the asking price.

The V2 Supersprint header technology is finally available as a direct bolt on to the US spec vehicle! While the more expensive version is intended for use with high flow SS cats or the SS straight pipes/ high-flow cats- this header is more affordable than ever and quality is outstanding. At this price, owning a real Supersprint Vs. a knockoff header is within most enthusiast reach.

The engineers at Supersprint realize that for maximum performance, exhaust development must begin at the exhaust ports (the cylinder head). This is why Supersprint has the largest variety of racing header systems in the world today: Applications that fit well and make amazing power gains next to all competitors.

Each Supersprint header incorporates CNC laser cut port matched flanges. Primary tubes that are mandrel bent using the latest CNC tube bending equipment; with special tooling Supersprint has been able to keep weld joints to a minimum for added reliability. The fully appointed R&D department uses the latest in prototyping equipment along with the reliability and accuracy of a MAHA "all wheel drive" chassis dyno to gauge results. With over 50 years in performance exhaust development they have earned the confidence of many of Europe's most respected tuners.

There is no doubt to us at VAC that aside from the Supersprint header-Highflow cat/Testpipe combo, this is the most powerful combination available!
With its excellent fitment this is the best Bolt-on header available for the E46 M3 and the Z4 M.

• New FLANGED design will fit to factory Section-1 on both E46 M3s and Z4 M coupes and Roadsters.

  VAC Tech Note:
  This newest header design is flanged and designed as a direct bolt on to the factory BMW exhaust or aftermarket rasp pipe on US spec E46 M3s. Stepped pipes for max power gains.
  Removes OE Catalytic Converters; Not street legal for use in CA. We do offer high flow headers that install in Section 1 if you wish to use these to pass emissions testing.
