“BROMBACHER” MUFFLERS are vastly different than the common aftermarket, “baffle plate and packing” type mufflers. Our mufflers are uniquely made with double perforated sound absorption tubes. These tubes are made in a trapezoidal pattern and are perforated with varying diameters, which isolates and dampens unwanted drone frequencies. In relation to performance, they produce much less flow restriction at higher gas velocities, which translates to larger horsepower gains at higher RPMs. Also they prevent a total loss of backpressure at lower rpms, so low end torque loss is minimized. Perhaps the greatest benefit of the “open architecture” design, is the strong, linear, firing-order dominated flat-6 Porsche® sound with aggressive gurgling and crackling off throttle.

THE CATALYTIC CONVERTER cores used in this system are the most advanced in the industry. They are produced by HJS in Germany and are a 200 CPSI (cell per square inch) tri-metal design. Tri-Metal cats are the freest flowing and environmentally friendly aftermarket cats produced today. Tri-metal catalytic converters are Rhodium, Platinum and Iridium coated and perform all three necessary and mandated reactions to prevent pollution. Reduction of nitrogen oxides to nitrogen and oxygen, oxidation of carbon monoxide to carbon dioxide and oxidation of unburnt hydrocarbons to carbon dioxide and water simultaneously. But we didn't stop there with these catalytic converters; we also opted for the most expensive HJS “HD” cores. The new generation of HJS high performance catalysts is characterized by 30 % less weight and 15% less backpressure. They are nicknamed “HD” for high durability matrix design catalytic converters. They have a “SM-matrix” (winding of three flat and corrugated foils) and a special connection to the matrix sheath (see picture below), which equates to extremely high flow and durability for track and street use. Many of our competition simply state the cells per square inch or “German Cats” but they are not specific as this portion of any exhaust system is THE MOST EXPENSIVE component. We choose to include the best cores available on the market to ensure years of trouble free operation, reduce weight, increase horsepower and protect the environment.

THE ENTIRE “BROMBACHER” EXHAUST LINE is manufactured by M&M Exhaust, GmbH in Germany. “Brombacher” exhausts are engineered for the discerning Porsche® owner and offer unmatched performance, unparalleled quality, and incredible value. They are tested comprehensively for flow rate and characteristics, thermal stress, resistance to cracking, and longevity. To further ensure quality, all of our exhaust systems meet the material standards of the German independent testing agency TÜV; whose quality standards are among some of the strictest in the world. All this research, development and testing ensures maximum horsepower gains throughout a broad power band; all while maintaining reasonable sound levels for the street and provide a distinct, sporty exhaust note that is purely Porsche®.
