In our relentless quest to meet all of our customers exhaust needs; we wanted to create a system that retains the OEM headers and 600 cell cats. The benefits are 3 fold, you can pass emissions with ease, you don’t need to run a software file (for those who are concerned about warranty) and you have a beautiful sounding system. But we didn’t stop there, our system also makes substantial power without drone!! We noted a + 15 crank hp & + 14 crank torque gain, predominantly in the mid and top end. The increase in mass and velocity of exhaust flow reduced backpressure and also thermal stress. This system retains the factory vacuum lines so that you can select the sound you want. It is factory quiet with the valves closed and give you much more aggressive deep tones with the valves open. Perfect for those in tune with shift points on the track.

This Brombacher muffler is factory stamped externally; unlike our competitors systems. This outer shell dampens and eliminates unwanted frequencies and ensures no resonance or drone in the cabin. The end result is a strong, linear, firing-order dominated flat-6 Porsche sound. In addition, each of our exhaust products have been extensively tested on both a chassis and engine dyno as well as logged thousands of miles on both the street and at the track. 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.

For vehicles without factory Exhaust System with valves, order Electronic Control (BES KLS000 001) separately.
