Transform your Porsche 991 Turbo and Turbo S with Redstar's Race-X system - a precision-engineered pairing of a muffler-replacement exhaust and a high-flow catted section tailored for 2014-2017 Porsche 991 Turbo / Turbo S and 2017-2019 Porsche 991.2 Turbo / Turbo S. Ideal for enthusiasts searching for performance exhaust or downpipes upgrades, this package is designed as a direct bolt-on solution that integrates seamlessly with factory connections and mounting points.
Engineered to open up exhaust flow, the Redstar configuration delivers significant power gains, faster spool-up and sharper throttle response while adding a richer, more engaging exhaust note. Optional OEM-style heat shielding cuts radiant exhaust temperatures by up to 80% to help protect temperature-sensitive components. Choose between HJS HD 200cpsi or GESI GEN2 400cpsi catalytic converters, with a Competition/Catless option for track-focused builds.
Built for durability and consistent performance, every assembly is crafted from 2.0mm wall 304 stainless steel, fully TIG welded and back purged, and finished with OEM-spec V-band flanges. As with all Redstar products, the system is a true bolt-on upgrade backed by a limited lifetime warranty and informed by motorsport-inspired manufacturing discipline.
Available Options
