Unlock the performance potential of your 2025+ Range Rover and Range Rover Sport NC11 4.4L twin-turbo V8 with Redstar's Primary Downpipes. Designed as a direct bolt-on replacement for the restrictive factory primary sections, these precision-built downpipes deliver immediate gains in power, throttle response and turbo spool.
For owners seeking the most impactful single exhaust modification, the primary downpipes represent the essential first step. By relieving backpressure at the most critical point in the exhaust system, the primaries sharpen response and add a noticeably richer exhaust note while maintaining compatibility with factory secondary sections.
Built to Redstar's exacting 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 precision-engineered performance upgrade that fits 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.
