Product Description

The Fabspeed Catback Competition Race X-Pipe is a premium performance exhaust system engineered specifically for Porsche 991.2 GT3 and GT3 RS (2014–2019) platforms. Designed as a lightweight bolt-on upgrade, this exhaust replaces the heavy and restrictive stock mufflers with a free-flowing tuned X-pipe layout that enhances exhaust scavenging, reduces backpressure, and produces a more aggressive GT3-style exhaust note without sacrificing street legality. It’s ideal for spirited driving, performance events, or track days where weight savings and sound quality matter most.
