Unleash the character of your 2005-2010 Porsche 997.1 911 Turbo and Turbo S with Redstar performance exhaust downpipes engineered for maximum flow, response and sound. Designed as a true 100% bolt-on upgrade, they integrate seamlessly with OEM-spec interfaces to deliver uncompromised performance for road or track-focused builds.

Expect a significant power gain, huge weight saving, faster spool-up and better throttle response, complemented by reduced underbonnet temperatures that help support turbocharger longevity. Specify Redstar's OEM-style heat shielding to cut radiant heat by up to 80% for enhanced protection of nearby components. The system also adds a refined, more engaging exhaust tone that suits the 997.1 TurboÕs character.

Built with engineering rigour, every Redstar system is 100% TIG welded and back purged for strength and consistency, and finished with OEM-spec flanges for reliable sealing. For the ultimate specification, Inconel 625 construction delivers a high-pitched, ripping exotic soundtrack, surpasses stainless steel in weight reduction and sound quality, and is around 100 times more durable than titanium. Redstar performance exhaust solutions are crafted to deliver precision, longevity and unmistakable sound.
