Cat-Back Exhaust System

The Circuit Werks cat-back exhaust system is designed for the 2009-2012 Porsche Boxster and Cayman 987.2 Base and S models. The system includes twin, angle-cut, 3.5-inch (89mm) polished finished tips that are adjustable vertically and horizontally to ensure a perfect fit.

This exhaust system aims to improve the sound and gain horsepower during normal driving conditions, offering a subtle sound at low RPMs that deepens into a sport-tuned tone when accelerated. It bolts onto OEM headers or aftermarket performance headers with supplied hardware and gaskets. Note that the system does not include installation instructions, but is considered simple for those with prior exhaust system installation experience.
