Upgrade the sound and performance character of your Porsche 991 Turbo / Turbo S with the STRATEC Grade 5 Titanium Valved Exhaust System. Designed to sharpen exhaust tone and enhance response, this system delivers a crisp, high-frequency motorsport-inspired sound with dual-mode flexibility for aggressive driving or refined cruising.
Engineered with CFD-optimized manifolds, a center X-pipe, and a valved titanium rear section, this exhaust improves exhaust flow, refines sound quality, and minimizes unwanted drone. With valves open, it produces a raw, sharp, race-inspired tone with aggressive shift pops. With valves closed, sound levels are reduced for a calmer, more comfortable cabin experience.
