Overview

The Fabspeed Long Tube Competition Race Header System is a performance exhaust component designed for Porsche 991.2 GT3 and GT3 RS vehicles from 2017 onwards. Constructed from 14-16 gauge T304 stainless steel and hand TIG welded, this system offers improved flow and a more aggressive sports car sound. It replaces the OEM center muffler, providing a weight savings of 40 lbs (18.1 kg) from the rear of the vehicle and is designed to bolt onto the OEM Porsche catalytic converters, remaining CAT-BACK emissions legal. The system is engineered to retain Sport Mode control when used with factory GT3 side mufflers and PSE systems, and is backed by a Fabspeed Lifetime Warranty.
