Topgear's new decat downpipes for the Porsche 718 Cayman/ Boxster GTS & GT4 delivers smooth power and aggressive sound.

This downpipe is a direct replacement for the factory downpipe/catalyst assembly. It is built from 304-grade stainless steel, which comes with Topgear's Lifetime Warranty. The shape of the unit was optimized for high flow with smooth bends and large, diameter tubing. This allows it to deliver the increased power, torque, and throttle response you want without sacrificing any performance at all.

The heat shield provided on these downpipes is built for extremely high temperatures and can withstand almost all temperatures possible from the engine.

Power increases are immediately noticeable, especially in the mid-range and at high RPMs. An increase in BHP is guaranteed with this part.
