The Active Autowerke BMW E46 M3 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 rob much desired horsepower. Following the famed BMW E46 M3 CSL headers, each individual header runner of the Active Autowerke header is cut to a matched equal length to ensure a consistent exhaust scavenging (tolerance in lengths vary by bends to a mean average of 10-20mm).
They are suitable for naturally aspirated and supercharged forced induction applications, Active Autowerke’s BMW E46 M3 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. Add on the AA BMW M3 Software Tune for even more power!

note: designed for off-road use, car will have CEL without Active Autowerke Software Upgrade for Off-Road use
