Transform your Porsche Cayenne and Cayenne E-Hybrid E839 3.0T single-turbo with the Redstar performance exhaust downpipe. Designed specifically for the 3.0t single-turbo platform, this big-bore downpipe replaces the restrictive factory section to unlock greater flow and efficiency where it matters most.

The smooth-transition geometry reduces backpressure, sharpening turbo spool and throttle response while delivering meaningful power gains and a richer, more engaging exhaust note. Pair it with Redstar's OEM-style heat shielding to cut radiant exhaust heat by up to 80%, helping to protect nearby components and support turbo longevity under sustained load.

Built with motorsport-inspired attention to detail and engineered for precise fitment, this Redstar downpipe integrates as a true bolt-on upgrade using OEM-style interfaces. With multiple configurations available, including GESI GEN2 400cpsi catalytic converters and optional heat shielding, Redstar gives Cayenne and Cayenne E-Hybrid owners a refined, high-performance solution that elevates sound, response, and driving enjoyment.

Available Options

  • 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.

  • Noticeable power and torque gains
  • Sharper throttle response with quicker turbo spool
  • Lower under bonnet temperatures for improved component protection
  • Enhanced, sportier exhaust note
