Description
Explore Kline’s exhaust range for the Porsche 981 Cayman / GT4. Select the exact configuration and material for the parts you need.
Kline uses X-pipe geometry in this exhaust range to shape the exhaust note. The valved rear-system configurations provide different sound paths with the valves open or closed. An Inconel 625 version is available for the configurations shown in the selector. The stainless-steel configurations use the 304-grade material described by Kline. The 100-cell and 200-cell designations identify HJS catalytic-converter options in Kline’s price list.
Application and fitment
Porsche 981 Cayman / GT4. The DECAT manifold configuration is specifically listed for the 981 Cayman GT4. Other configurations retain the Cayman/GT4 application supplied by Kline.
The configuration names below retain Kline’s vehicle and component restrictions. Each selection is priced separately; choosing a cat pipe, manifold, or rear section does not include the other components shown in the gallery.
