Transform the soundtrack and response of your 2025+ Bentley Continental GT Speed, GTC Speed and Flying Spur Speed with Redstar performance exhaust downpipes engineered specifically for the 4.0L V8 Hybrid. Only fits V8 4.0 Hybrid - does not fit W12. Designed to integrate with the OEM split layout for precise fitment and seamless compatibility with factory mounting points.
Developed using advanced CAD methods and motorsport-inspired fabrication, these flow-optimised downpipes reduce backpressure to sharpen throttle response, aid faster turbo spool and unlock meaningful power gains. Optional OEM-style heat shielding cuts radiant exhaust heat by up to 80%, helping contain under-bonnet temperatures. Choose high-performance catalytic converter options including HJS HD 200cpsi or GESI GEN2 400cpsi, both rated for 1000hp applications, with improved exhaust flow over factory components. OPF options are available for euro emission controlled vehicles only.
Every Redstar downpipe is built as a true bolt-on upgrade for the Bentley 4.0L V8 Hybrid, delivering a richer, more engaging exhaust note alongside proven performance advantages. Backed by Redstar’s engineering focus and meticulous quality control, this system offers the ideal balance of precision fit, durability and authentic Redstar sound.
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.
- OPF: For euro emission controlled vehicles.
