KLINE INNOVATION KL-POR-991GT2RS-RACE-RS-SS Exhaust System Valvetronic Race 3" for PORSCHE (991) GT2RS

The factory titanium exhaust of 991 GT2 RS, while sounding better than the previous generation 997, still doesn't reflect the raw nature of this supercar, but Kline engineers are xperts at turning the faint sounds of a turbocharger into an exotic supercar howl!

Sound

Building on the design innovations and success of the 996 and 997 models, the starting point for the 991 GT2 RS exhaust system was set high. The signature perfect x-pipe geometry, harmonically tuned mufflers, Inconel 625 and proprietary acoustic muffler packing materials resulted in a system that has become renowned for its perfect sound. There is no rumble, and at high rpm and when the gas pedal is pressed hard, there is an incendiary howl with an elevated tone. Using the stock valvetronic vacuum system, the company was able to install the company's proprietary valvetronic mufflers, resulting in an even more discreet ride on closed valves and a more aggressive sound on open valves.

Performance

Comes with decats for optimal performance and sound, as well as 100 or 200 cell HJS HDPE catalysts. The biggest power gains with decats are 42 hp and 59 nm. The 100 and 200 cell catalysts give 22 hp and 18 hp, respectively.
