E46 M3 Supersprint Step Header Design
This patented design is quite unique in that it offers a smaller diameter primary tube that starts 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.
The engineers at Supersprint realize that for maximum performance, exhaust development must begin at the exhaust ports of the cylinder head. This is why Supersprint has the largest variety of racing header systems in the world today. Each header incorporates CNC laser cut port matched flanges. Primary tubes 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 proto typing equipment along with the reliability and accuracy of a MAHA "all wheel drive" chassis dyno. With over 50 years in performance exhaust development they have earned the confidence of many of Europe's most respected tuners.
Note: For e46 M3 (2000-2006), must be used with 022 044 002 over sized metallic cat or 022 044 012 over sized connecting pipe.
