Unleash your Bentley and Porsche with Redstar performance exhaust downpipes engineered for top primary placement on twin-turbo 4.0 V8 applications. Precisely matched to 2025+ Bentley Continental GT|GTC Speed 4.0L V8 Hybrid and 2025+ Bentley Flying Spur Speed 4.0L V8 Hybrid, plus 2019-2024 Continental GT and 2020-2024 Flying Spur twin-turbocharged 4.0L V8. Also suits 2019-2023 Porsche Panamera 971.1/971.2 GTS, 2016-2023 Panamera 971.1/971.2, 2017-2023 Panamera 971.1/971.2 Turbo S E-Hybrid, and 2024+ Panamera 976 GTS, 976 Turbo E-Hybrid, 976 Turbo S E-Hybrid. Top Primary downpipe placement only. For Bentley applications, only fits the 4.0 V8 and 4.0 V8 Hybrid - does not fit W12.

By optimising the primary downpipe section, Redstar reduces backpressure for significant power gains, faster turbo spool and crisper throttle response, while delivering a deeper, more engaging exhaust note. Pair with Redstar OEM-style heat shielding to cut radiant heat by up to 80%, lowering under-bonnet temperatures to protect nearby components and help prolong turbocharger life.

Every Redstar system is built for durability and precision integration: 2.0mm wall 304 stainless steel, 100% TIG welded and back purged with OEM-spec CNC machined flanges and factory-style brackets for a true bolt-on install. Choose between HJS HD 200cpsi or GESI GEN2 400cpsi catalytic converter options to meet your performance goals, and add Redstar heat shielding for motorsport-inspired thermal control. Redstar downpipes bring race-grade manufacturing to your road car with reliability you can trust.

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.

  • 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.
