Unleash your Audi with Redstar performance exhaust hardware engineered for the C8 platform. This downpipes and resonator delete package is developed for the biturbo RS7 Sportback Sedan / RS7 Performance and RS6 Avant / RS6 Performance / RS6 GT, with an available V-band downpipe to resonator delete connection for a precise fit.
Through careful CAD development, flow-focused geometry and motorsport-inspired manufacturing, this system reduces exhaust restriction to sharpen throttle response and enhance power delivery. It is an ideal foundation for higher-output builds including big turbo upgrades. Pair it with Redstar OEM-style heat shielding to cut radiant underbonnet heat by up to 80%.
Built with Redstar quality throughout, the assembly is designed as a true bolt-on upgrade that integrates with OEM mounting points. Every component reflects an engineering-first approach to durability and performance, making it a compelling performance exhaust solution for Audi C8 RS6 and RS7 owners seeking improved flow, a more assertive sound, and long-term reliability from their Redstar downpipes and resonator delete.
Available Options
- HJS HD 200cpsi Catalytic Converters: Engineered in Germany and trusted worldwide, the HJS 200cpsi ultra high-performance cats are rated for over 1000hp. Renowned for exceptional flow, durability, and consistent quality, these converters set the benchmark for high-output applications. Ideal for drivers demanding maximum performance without compromise.
- GESI GEN2 400cpsi Catalytic Converters: The latest GEN2 series from GESI is rated to support up to 1000hp while offering smoother exhaust flow and improved efficiency compared with factory units. Featuring advanced emissions technology for optimal catalyst function at high flow rates. A strong choice for those seeking significant performance gains with refined operation.
- OEM-Style Heat Shielding: Redstar's signature thermal management system reduces radiant exhaust heat by up to 80%.
