The Active Autowerke E46 M3 Performance Header is designed to increase exhaust flow without losing power, which can sometimes be a tricky proposition. These headers are developed to create optimum flow and eliminate restriction that robs much-desired horsepower.
Suitable for naturally aspirated and supercharged forced induction applications, Active Autowerke’s E46 m3’S Performance Headers are made out of 100% 304 stainless steel, making durability a worry of the past. Are they difficult to install? Absolutely not! Robust exhaust flanges with recessed mounting holes make it easy to install. If you can turn a ratchet, you’ll be on your way to increasing horsepower. The factory exhaust catalysts are removed in the process, making this solution recommended for off-road applications.
