Overview

Fabspeed GT4 RS Valved X-Pipe Exhaust: a valved X-pipe cat-back exhaust that gives the GT4 RS a higher-pitched wail while keeping the factory PSE button for a quiet mode, for the 2023-2025 Porsche 718 GT4 RS. It saves 3 lbs over the factory parts it replaces.

Sound

In Fabspeed's words: "Wondering why your GT4 RS doesn’t have the same high pitched scream of the GT3? Our Valvetronic X-Pipe is the solution!"

Valves

Genuine Helical electric exhaust valves made in the UK work with the factory Porsche Sport Exhaust (PSE) button, so you keep a quiet mode and a loud mode.

Cast X-pipe and resonators

A signature cast X-pipe merges the two cylinder banks for a higher-pitched flat-six note, and Helmholtz resonator technology cancels the frequencies that cause drone.

Tip options

Choose carbon fiber, satin black, polished stainless, brushed single-wall stainless or brushed stainless turndown tips, or reuse your factory tips. Turndown tips lower the sound level for track days with noise limits.

Installation

Bolt-on cat-back installation with no cutting or welding, using the factory mounting points. Professional installation is recommended.
