Description
The CARGRAPHIC Final Silencer Replacement X-Pipe (SUPER SOUND+ Version) transforms the sound and performance of the Porsche 991 Turbo and Turbo S 3.8L. Replacing the restrictive factory rear silencer with a precision-engineered “X” crossover pipe, this system delivers a more aggressive SUPER SOUND+ exhaust note while maintaining zero drone or resonance — even when paired with other CARGRAPHIC exhaust components.
Constructed from lightweight SS304L stainless steel with CNC mandrel-bent pipework, reinforced laser-cut brackets, and olive/bandclamp/sleeve connections, it ensures durability, optimal flow, and an easy, precise fitment. The result is reduced backpressure, improved throttle response, lower operating temperatures, and dyno-proven gains of up to +7 kW (10 PS) and +10 Nm torque. Designed for use with the factory tailpipes, this upgrade delivers sharper, crisper acoustics that increase in intensity with revs, while staying true to the Porsche character.
Fitment:
- Porsche 991.1 Turbo / Turbo S 3.8L (2014–2016)
- Porsche 991.2 Turbo / Turbo S 3.8L (2017–2019)
