Transform your 2016-2020 Porsche Panamera 4S 971 2.9L V6 Twin Turbo or 2016-2020 Porsche Panamera 4 E-Hybrid 971 2.9L V6 Twin Turbo with the Redstar Exhaust Secondary Cat Delete downpipes. Engineered to integrate with the OEM split design, this secondary cat delete replaces the factory secondary catalytic converter section and installs as a true bolt-on performance exhaust upgrade.

By removing the restrictive secondary catalysts, exhaust flow is dramatically improved for faster turbo spool, sharper throttle response, and a noticeable increase in power and torque. The refined, sportier exhaust tone enhances driver engagement without triggering a check engine light. Add Redstar’s OEM-style heat shielding option to reduce radiant heat by up to 80% for cooler under-bonnet conditions and greater thermal control.

Built for longevity and precision, each Redstar system uses premium 2.0mm wall 304 stainless steel, is 100% TIG welded and back purged, and features OEM-spec CNC machined flanges with all brackets and mounts as on the OEM unit. Trusted by enthusiasts for fit, finish, and durability, Redstar downpipes deliver a seamless upgrade for your Panamera’s performance exhaust.

Available Options

  • 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."
