Redstar BMW F90 M5/M8 Complete Downpipe System
Pairs well with
Unleash the potential of your BMW with Redstar performance exhaust downpipes engineered specifically for the 2017-2023 BMW M5 F90 and 2018-2023 BMW M5 Competition F90 4.4 L S63 twin-turbocharged V8, as well as the 2019-2023 BMW M8 F91, F92, and F93. This complete kit replaces the restrictive factory sections directly after the turbos and includes Upper Primary and Secondary Downpipes, utilising the OEM split slip-on design for precise alignment and a true bolt-on installation.
Flow-optimised geometry reduces backpressure for faster spool and sharper throttle response, translating to significant real-world gains and a more engaging driving experience. Optional OEM-style heat shielding with a ceramic inner liner cuts radiant heat by up to 80%, helping to control under-bonnet temperatures while enhancing turbo longevity and adding a richer, more characterful exhaust tone.
Built for durability and performance, every Redstar system is crafted from 2.0 mm wall 304 stainless steel, 100% TIG welded and back purged, and finished with OEM-spec V-band flanges and factory-style brackets. Available with HJS 200cpsi or GESI GEN2 400cpsi catalytic converter options and Redstar’s motorsport-inspired heat shielding, this downpipe set blends precision fitment with proven engineering for the BMW M5 and M8 platforms.
