Active Autowerke E46 M3 Gen 4 Headers by PSI

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 rob 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. These are a very close design to the OEM CSL header with the US locations for O2 bungs and temperature sensor, by far one of the best sets of headers made for the S54.

Here at PSI, these are used on ALL of our S/C M3s and S54 builds.

The factory exhaust catalysts are removed in the process, making this solution recommended for off-road applications.

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

Key Features:

-Creates optimum flow and eliminates restriction
-Dyno Tested to provide improved HP and torque gains
-Polished 100% 304 stainless steel construction
-Designed for Street and/or Track Use
-Bolt On Design with Precise Fitment
