Lightweight Titanium • OEM Valve Integration • Race-Inspired Sound
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.
We know every GT4 RS owner has their own taste in sound—so this system is offered in three unique configurations:
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.
Constructed from Grade 5 Titanium

"A musical instrument fortunate to pair with the 4RS"
"I have a Valvetronic titanium exhaust system on my 2023 Caymen GT4 RS. The sound is just incredible. It could not be better. Valves closed it sounds good, but valves open it just sounds magnificent. It is a roar through the throat of the gods. The fit and finish are impeccable, but the sound is just so satisfying. Certainly this is something every enthusiast would want and I know once you here it you will be dying to have. Thank you Valvetronic for such a great product. I would send all of the Porsche Club to your doorstep."
