Unleash the performance of your BMW with Redstar performance exhaust downpipes for S68 platforms - precisely tailored for the 2023+ X5 G05 M60i, X6 G06 M60i, X7 G07 M60i, 2023+ Alpina XB7, 2024+ F95 X5M LCI S68, 2024+ F96 X6M LCI S68, and 2023+ BMW XM G09 4.4L including XM Label Red. Designed as a true bolt-on solution, these downpipes replace both primary and secondary catalytic converters to remove major factory restrictions.
Optimised exhaust flow reduces backpressure, sharpening throttle response, improving turbo spool, and unlocking meaningful power gains while delivering a deeper, more assertive exhaust note. For refined control of heat management and under-bonnet temperatures, the optional OEM-style heat shielding cuts radiant exhaust heat by up to 80%. Drivers seeking high-output capability can select HJS HD 200cpsi ultra high-performance catalytic converters for exceptional flow with robust durability.
Every Redstar system is built for longevity and precision fitment, featuring 2.0mm wall 304 stainless steel, 100% TIG-welded and back-purged construction, OEM-spec flanges, and factory-style brackets. Developed to integrate seamlessly with OEM mounting points, Redstar downpipes deliver a premium performance exhaust upgrade for BMW S68 applications with the sound, response, and quality enthusiasts expect.
