The Porsche 992 carrera. Progressive yet retro styling cues, and a twin turbo flat 6 producing 380hp, the 992 is a striking and powerful machine. The exhaust however, stifled by manufacturer and emissions restrictions, is somewhat lackluster. Here at kline, we are experts in turning dull turbo sounds into an exotic supercar wail.

The Sound

Removal of the heavy chambered rear silencer, and replacing it with a lightweight F1 grade Inconel 625 X pipe, and Fully bypassable lightweight Inconel silencers, sheds a significant amount of weight, as well as raising the pitch of the exhaust into a more exotic tonal range. Removal of the OPF and catalysts, and replacing them with either HJS motorsport catalysts, or De-cat pipes, opens the sound up significantly, complementing and accentuating the high pitched silencer section, into an exotic scream. The Kline innovation rear valvetronic setup, means that the car can be driven in stealth mode with the valves closed, however a raw unhindered sound can be achieved with valves open. Addition of our beautifully crafted F1 grade Pre Preg carbon fiber exhaust tips complemets the exhaust perfectly.


As with all Porsche turbo platforms, the potential for tuning is huge. Replacing the stock catalysts, with our de-cat pipes, and correcting the subsequent af ratios will yield over 40hp, and 55nm of torque. With the addition of a full ecu remap, upward of 80hp gains can be expected.
