Unleash your McLaren with Redstar Performance Downpipes engineered for the 3.8L twin-turbocharged V8 M838T found in the 600LT, MP4-12C, 650S, 675LT, 540C, 570S, 570GT and P1. This performance exhaust upgrade replaces the restrictive OEM downpipes to open up the system and deliver the racing inspired sound McLaren owners love, complete with cracks and burbles.
By reducing backpressure, these downpipes promote quicker turbo spool and sharper throttle response while unlocking significant power potential. Expect a noticeable weight saving compared with the factory exhaust and lower under-bonnet temperatures, especially when paired with Redstar OEM-style heat shielding that cuts radiant heat by up to 80%. Choose high-performance catted options or a competition catless configuration to suit your goals.
Built for durability and precision, Redstar downpipes use 3.5 inch 2.0mm wall 304 stainless steel with TIG welded, back-purged construction and OEM-spec V-band flanges for a true bolt-on fit. Optional HJS HD 200cpsi converters are rated over 1000hp, and GESI GEN2 400cpsi cats support up to 1000hp and withstand up to 925C core temperature. Redstar brings proven quality, value and sound in one focused upgrade.
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.
