Product Details

Precision-built from premium materials and tailored specifically for the 981 flat-six engine the Kline Innovation Stainless Steel or lightweight Inconel system enhances both performance and perfect sound—making it a favorite among enthusiasts seeking a perfect blend of race-inspired performance and refined German engineering.

THE SOUND

Building on our highly revered Porsche turbo range, we have incorporated many of the same design features into our Cayman R, 1D CLR X pipe for that incendiary howl at higher rpm, harmonically tuned silencers, and ultra-thin Inconel 625 for that “Unique to Kline” sound.
The Kline Cayman R system also incorporates a valvetronic design, allowing the car to be run stealthily on valve closed, while attaining an unhindered raw scream, and optimum performance when the valves are opened.
Available in Decat for optimum sound and performance or a 200 cell high flow sports cats. The cats section is modular, allowing the cats to be swapped with decat very rapidly, depending on intended use.
