Redstar BMW F90 M5/F95 X5M/F96 X6M/M8 Primary Downpipes
Pairs well with
Unleash sharper performance from your BMW M5 F90 4.4 L S63 twin-turbocharged V8, BMW X5M F95, BMW X6M F96 and BMW M8 F91 F92 F93 with Redstar performance exhaust downpipes. These upper primary slip-on style downpipes are engineered for precise fitment and optimised flow, replacing the restrictive factory primary sections while retaining full compatibility with the OEM system.
By reducing exhaust restriction, they deliver quicker turbo spool, crisper throttle response and measurable power gains, while lowering under-bonnet heat to help protect components and support turbo longevity. Configure your system with premium catalytic options - HJS HD 200cpsi ultra high-performance converters rated for 1000+ hp or GESI GEN2 400cpsi converters rated for 1000 hp - and add OEM-style heat shielding with a ceramic inner liner for dramatic reductions in radiant heat. The result is a deeper, more engaging exhaust note without compromising daily drivability.
Built for durability and accuracy, each Redstar downpipe uses 2.0mm wall 304 stainless steel with 100% TIG welding and back purging, OEM-spec V-band flanges, and factory-style brackets and mounts. The true bolt-on design ensures straightforward installation and a leak-free seal. Trusted by enthusiasts for robust construction, precise fit and repeatable results, Redstar downpipes are the definitive upgrade for S63-powered BMW performance cars.
