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 au00a0matched 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.

Take it from Robert Chang, BMWCC 2013 National Champion for C-MOD in his E46 M3 powered by the Active Autowerke headers."...These headers help to deliver the power when needed..." You too can help unleash the hidden power in your E46 M3. u00a0


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

Input from Karl Hugh, Head of Engineering, Active Autowerke. "...the SECTION 1 with 100 cell race style cats do not lose any power!!!! Even when we try them on the BMW E46 M3 powered with the 600 horsepower Supercharger, there is no loss in power!!!..."

Came based on a work buddies recommendation. I was late by 30 minutes, confused my appointment time. But, 10/10 would come back. Came for a Downpipe and midpipe install. Not only was the gentleman accommodating, He ran into some issues, staff helped me out and pointed me into the right direction and got me going! They got my business and wouldn’t go anywhere else again!
