Unleash your 2020+ Mercedes-AMG GLE63 / GLE63 S W167 / C167 / V167 C293 and GLS63 / GLS63 S W167 / X167 / C293 with Redstar performance exhaust downpipes engineered for the 4.0 biturbo engine. These precision downpipes replace the restrictive factory units to open up exhaust flow, pairing OE fitment with motorsport know-how. Options include high-efficiency sports cats and OPF support for European emission controlled cars.

Reverse engineered for optimal gas velocity, the Redstar design sharpens throttle response, promotes faster spool, and delivers significant power gains while adding a deeper, more assertive tone. Redstar's OEM-style heat shielding with ceramic insulation is available to cut radiant exhaust heat by up to 80%, helping protect surrounding components and sustain turbocharger longevity. Choose HJS HD 200cpsi or GESI GEN2 400cpsi catalysts to tailor sound and performance to your build.

Every system is built for durability and seamless installation: 2.0mm wall 304 stainless steel, 100% TIG welded and back purged, with OEM-spec V-band flanges and factory-style brackets. It is a true bolt-on upgrade for LHD and RHD vehicles, engineered to integrate cleanly with the original mounting points. Redstar downpipes embody precision manufacturing and reliable performance for the Mercedes-AMG GLE63 and GLS63 platforms.

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.
