E46 M3 High Flow Exhaust

bmw exhaust Active Autowerke has a wide array of products available for all BMW models ranging from early E36 models to the new E9X M3. Whether you want a simple bolt on upgrade or the full Force Induction Package, Active Autowerke has it all.

Active Autowerke has recently expanded on their signature Line including Short shift Kits and their world renown Exhaust systems. Like the new E46 M3 High Flow Exhaust.

Designed specifically for the E46 M3, the all-stainless Active Autowerke Generation 4 is the most innovative cat-back exhaust to date from Active Autowerke. Its precision-tuned straight-thru 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 design employs inspired pipe routing and optimum diameters to enable the Gen 4 to literally unleash horsepower without restrictions.

Sporting the same classic 80mm tips as Gen 3, everything else about Gen 4 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 M3 with no rear exhaust vs one with the Gen 4 system installed. Zero power loss was measured with the Gen 4 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 4’s superb performance characteristics.
With its flush aerodynamic fit, high-polish 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.

A special reduced price is available so you can buy the system for $1,275. You can also browse on our store for Active Autowerke parts.
