Porsche GT4 RS – Titanium Valved Exhaust System

Lightweight Titanium • OEM Valve Integration • Race-Inspired Sound

Overview

For a car as special as the Porsche GT4 RS, only the best will do. The Valvetronic Titanium Valved Exhaust System is engineered to amplify everything that makes the GT4 RS exceptional—its raw motorsport spirit, lightweight engineering, and aggressive styling—while unlocking the exhaust note it truly deserves.

Constructed entirely from Grade 5 titanium, this system offers a dramatic weight reduction and unparalleled durability. Every component has been precision TIG welded and designed for seamless OEM-level fitment.

Sound Dynamics

We know every GT4 RS owner has their own taste in sound—so this system is offered in three unique configurations:

• Over-Axle Pipes Only – Adds volume and sharpens tone.

• Rear Section Only – Features a large cross-section X-pipe for refined, exotic sound quality.

• Full System – The ultimate choice for those seeking both sound and performance—volume from the over-axle pipes combined with tone and character from the rear section.

With valves closed, the system keeps things refined for daily driving and neighborhood-friendly manners. With valves open, your GT4 RS transforms into a howling motorsport machine, delivering the most intoxicating sound experience possible.
