Transform the exhaust performance of your 2025+ Range Rover and Range Rover Sport powered by the all-new BMW-sourced NC11 4.4L twin-turbo V8. Redstar's Complete Downpipes System replaces the restrictive factory primary and secondary sections with flow-optimised, precision-engineered components that deliver significant gains in power, throttle response and turbo spool.

This full kit downpipe system should be the first exhaust modification for owners looking to unlock the true potential of the NC11 engine. By reducing backpressure throughout the entire exhaust path, the system produces a noticeably richer exhaust tone while helping protect turbocharger longevity through reduced under-bonnet temperatures when specified with Redstar's signature OEM-style heat shielding.

Built to Redstar's uncompromising standards, each assembly uses highest quality 2.0mm wall 304 stainless steel, is 100% TIG welded and back purged, and features OEM-spec V-band flanges with factory-style brackets and mounts. The result is a true bolt-on solution that integrates seamlessly and is backed by Redstar's limited lifetime warranty.

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. EPA Compliant catalytic converters have been third-party lab tested to meet or exceed local emissions standards in North America (excluding California).
• OEM-Style Heat Shielding: Redstar's signature thermal management system reduces radiant exhaust heat by up to 70-80%. 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. Includes straight tunable O2 spacers with 3 inserts to help prevent engine light conditions. Track use only - not for road use.
