The 991 turbo is the performance car benchmark. Being amazing at every task is no small feat but just like all turbo Porsches, it leaves much to be desired in the sound department. We solve the sound issue starting at the exhaust manifolds. running our CAD designed and CFD tested manifold setup helps increase the pitch of our exhaust to give a much more motorsport tone. When operating the system in the valves open mode, exhaust gasses, once passed through the turbos travel straight 13 inches out of the back of the car for an uncorrupted Porsche sound experience. When running in the valves closed mode, sound passes through 2 quad chambered mufflers in order to lower sound levels significantly. a Center X-pipe is added to smooth exhaust flow and eliminate drone. Its time to make your 991 Turbo sound like it always should have.
