 AA E46 M3 Signature Performance Exhaust

 

Active Autowerke BMW M3 Exhaust E46

 

Designed specifically for the E46 BMW M3 exhaust system, the all-stainless Active Autowerke Generation 6 is our most innovative cat-back exhaust to date. Its precision-tuned straight-through design with in line resonators offers an incomparable combination of power, sound and styling.

 

Well suited to both naturally aspirated and supercharged vehicles, this new and revolutionary BMW M3 Exhaust design employs inspired pipe routing and optimum diameters to enable the Gen 6 to literally unleash horsepower without restrictions. Sporting the same classic 80mm tips like the earlier versions, everything else about the Gen 6 is new. It’s lighter, stronger and more robust with a distinct sound unique to the generation. Does it work? You bet it does. Performance gains of 5-7 peak rear WHP can be expected. Is it really that free-flowing? Comparison dyno tests were run on an E46 BMW M3 with no rear exhaust vs one with the Gen 4 system installed. Zero power loss was measured with the Gen 6 in place.

 

Like we said, this thing is practically invisible! But you can sure hear it. Just listen for the rich, low frequency tone at idle to moderate RPMs. And the distinct, robust sound at higher RPMs validating Gen 6’s superb performance characteristics. Sporting a newer, more rounded look; an aerodynamic fit; New Brushed Finish and quad 80mm straight tips, this rig is considered by many enthusiasts to be the sleekest, most aggressive exhaust around.

 

Installation is simple, utilizing all the stock mount points with no rear valance mod required. Combined with our BMW M3 Sport Header, you can build the ultimate BMW M3 exhaust!

 AA E46 Signature Headers


Active Autowerke BMW E46 M3 Header




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.

 

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. 

 

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.

 

BMW exhaust header mounting hardware for BMW E46 M3 Plus, all the gasket hardware that you will need is all included.

 

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