Unleash a sharper, more responsive drive in your Porsche 911 Turbo and Turbo S with Redstar performance exhaust downpipes for the 2010-2013 Porsche 997.2 911 Turbo / Turbo S, 2014-2017 Porsche 991.1 Turbo / Turbo S, and 2017-2019 Porsche 991.2 Turbo / Turbo S. These precision-engineered downpipes replace the restrictive factory components to free exhaust flow and elevate the soundtrack.

Developed with a motorsport-inspired approach and CAD-guided geometry, the Redstar design focuses on reducing backpressure for faster spool and crisper throttle response, delivering significant performance gains and a richer, more engaging tone. Optional OEM-style heat shielding cuts radiant heat by up to 80% to help protect surrounding components and support turbo longevity. Catalyst options include HJS HD 200 cpsi and GESI GEN2 400 cpsi to suit your performance goals.

Built for quality and durability, every Redstar downpipe is manufactured from 2.0 mm wall 304 stainless steel, 100% TIG welded and back purged, and finished with OEM-spec V-band flanges. The system installs as a true bolt-on using factory-style brackets and mounts, reflecting RedstarÕs commitment to engineering excellence, sound quality, and long-term reliability.

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.
