Unleash the performance potential of your BMW E70 X5M and E71 X6M with Redstar performance exhaust downpipes for the S63 4.4-litre V8 bi-turbo. Purpose-built for these M models, the Redstar downpipes integrate with OEM mounting points as a true bolt-on upgrade to the factory locations, delivering a precise fit and dependable sealing.

Expect a significant step forward in drivability with quicker turbo spool, sharper throttle response and a more engaging exhaust tone. Optional OEM-style heat shielding reduces radiant heat by up to 80%, promoting greater thermal stability around the engine bay and supporting long-term turbocharger health.

Engineered for durability and consistency, each system uses 2.0mm wall 304 stainless steel with 100% TIG-welded, back-purged joints and OEM-spec 304SS flanges. All brackets and mounts mirror the OEM unit, ensuring straightforward installation and a robust, long-lasting connection. Redstar downpipes deliver the blend of precision, reliability and sound that performance enthusiasts expect from a premium Redstar performance exhaust upgrade.
