Transform your 2016-2021 Acura NSX NC1 3.5L Twin-Turbo V6 and 2022-2023 Acura NSX Type S with the Redstar full 3 inch performance exhaust - a complete downpipe-back system engineered for maximum flow and response. This system replaces the factory exhaust from the downpipes rearward and is not interchangeable with OEM downpipes or OEM exhaust. Featuring larger-than-stock flanges with zero neck-down, it targets the restrictive sections that limit performance.
By maintaining a true 3 inch flow path and eliminating bottlenecks, the Redstar system reduces backpressure to sharpen throttle response, aid faster spool, and unlock measurable power and torque gains. Optional OEM-style heat shielding cuts radiant exhaust heat by up to 80%, supporting thermal management under demanding conditions. Valve delete with simulators is integrated to complete the performance-focused configuration.
Built for longevity and precision, every assembly is 100% TIG welded and back purged using 2.0 mm wall 304 stainless steel and installs as a true bolt-on. Pair the Redstar performance exhaust with your preferred catalytic converter option, including HJS 200cpsi or GESI GEN2 400cpsi, to tailor sound and flow. Expect proven Redstar engineering, quality, and an unmistakable performance exhaust character for your NSX.
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%. Developed with motorsport-inspired materials and construction, it uses a multi-layer design of ceramic insulation and embossed stainless steel foil. Unlike wraps or coatings that degrade quickly, Redstar shielding delivers long-term durability and consistent protection for engine bay components.
- Competition/Catless: Maximum flow design for uncompromised performance. Delivers the most aggressive exhaust note and optimal power gains. Track use only - not for road use..
