Our Brombacher Edition 991.1 GT3 exhaust system varies greatly from designs that are common in the aftermarket. Our muffler is uniquely made with double perforated sound absorption tubes based on the Halbgegenstromprinzip (half counter current principle). The acoustic silencer absorption tubes are made in a trapezoidal pattern and are perforated with varying diameters. This design isolates and dampens the unwanted frequencies that create drone. Perforated tubes also create much less flow restriction than baffle plates at higher gas velocities, and consequently translates into larger horsepower and torque gains throughout the entire rev range. The resulting sound exhibited is a sonorous, linear-firing-order dominated flat 6 Porsche sound, which also gurgles and crackles off throttle. It is the closest to a Cup Car sound in nature. This sound is not a coincidence as our entire “Brombacher” line of exhausts is manufactured by M&M Exhaust, GmbH in Germany. They manufacture a multitude of Porsche Motorsport and Racing Exhausts. Each system is tested comprehensively for flow characteristics / rate, thermal stress, cracking, and longevity. Whether you are looking for the perfect street exhaust or one that can handle abuse at the track, look no further.
