Unleash the performance potential of your Aston Martin with Redstar performance exhaust downpipes engineered for the M177 4.0-litre twin-turbo V8. Precisely developed for the 2018+ DB11 and 2018+ Vantage, AMR and F1 Edition, this system targets the primary downpipes and replaces the restrictive primary Catalyst section located directly after the turbos. The result is a seamless, direct bolt-on solution tailored to these applications.

Designed around optimised flow geometry and validated through advanced development methods such as CAD modelling and flow-bench analysis, the Redstar design reduces backpressure to sharpen throttle response, speed up turbo spool and unlock measurable power gains. When optioned with OEM-style Heat Shielding, radiant exhaust heat is reduced by up to 80%, helping keep under-bonnet temperatures in check and supporting long-term turbo reliability. A richer, more engaging exhaust tone completes the transformation without compromising fitment.

Built for durability and precision, each system uses 2.0mm wall 304 stainless steel, is 100% TIG welded and back purged, and integrates with OEM-spec V-band flanges plus factory-style brackets and mounts. This is Redstar engineering at its finest - a true bolt-on upgrade that blends motorsport-inspired craftsmanship with factory-level fit and finish for your Aston Martin DB11 or Vantage M177.

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.
