Overview

Fabspeed 958.2 Cayenne Turbo Cat Bypass Pipes: secondary cat bypass pipes, for the 2015-2018 Porsche 958.2 Cayenne Turbo / Turbo S.

Design

These straight-through pipes replace the heavy, restrictive factory secondary catalytic converters. Fabspeed quotes sharper throttle response and a mild exhaust note improvement, with no check engine light.

Use

Cat bypass parts remove the catalytic converters and are sold for off-road and competition use only. They are not legal for use on public roads in the US.

Installation

Plan for a professional install. The part bolts to the factory mounting points, and the factory gaskets can be reused if they are in good condition. Re-torque the fasteners after the first heat cycle.
