Product Details

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.
