Sport Muffler 991.1 C2 / C4 - 3.4 L - Brombacher Edition

This muffler for the 991 is one of the most technically advanced mufflers for Porsche to date. Our muffler incorporates an X pipe design to dampen and eliminate unwanted frequencies otherwise known as “drone” and gives the system the added benefit of increased torque in the mid-range. The actual muffler is vastly different than the common baffle plated muffles stuffed with packing material that are common in the aftermarket. Ours are uniquely made with double perforated sound absorption tubes. The acoustic silencer absorption tubes are made in a trapezoidal pattern and are perforated with varying diameters, which isolate and dampen unwanted frequencies. Perforated tubes at higher gas velocities, present much less flow restriction than baffle plates and consequently translates into larger horsepower gains at higher RPMs. Also, they produce the aggressive gurgling sound and contribute to the low, deep tones that you hear. The exhaust tips are a dual 3.5” round design and are double walled to dissipate heat, which means that they won't tarnish as quickly as single walled tips. The design fit's the factory cut outs in the bumper perfectly and is mounted via a “Aero- Quip” ball style-connecting joint so they can be perfectly adjusted and centered.
