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.
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. Performance gains of 5-7 peak rear WHP can be expected. 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.
