THE EXHAUST CONNECTIONS are “AERO QUIP” connections. These “AERO QUIP” connections reduce weight as they only use one bolt and nut versus 3 found on most header / cat flanges. They also keep increase gas volume and gas velocity constant as the tubing diameter is kept consistent.

THE 100 CELL CATALYTICS are made with HJS cores. But we didn't stop there. They are 100 Cell HJS “HF” (High Flow) Tri-Metallic cats. They are meant for the track and will give you many, many years of service.

THE MUFFLER is vastly different than the common baffle plated mufflers stuffed with packing material that are common in the aftermarket. Ours are 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, which isolate and dampen the unwanted frequencies that create drone. These perforated tubes present 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.

THE EXHAUST TIPs are a 4.5” (116 mm) oval design and are double walled to dissipate heat, which means that they won't tarnish as quickly as single walled tips. The design fits the factory cut outs in the bumper perfectly and is mounted via the “Aero-Quip” ball style-connecting joint so it can be perfectly adjusted and centered.

All of the points made above are far more time consuming to manufacture and add expense to our products. But we choose these methods to ensure maximum horsepower gains throughout a broad power band; all while maintaining reasonable sound levels with an exotic exhaust note that is purely Porsche.
