Unleash the performance of your BMW X5M F95 and BMW X6M F96 with the Redstar Exhaust secondary cat delete. This upgrade replaces the lower secondary pipes with a Lower Secondary Slip style Downpipe, removing the secondary catalytic converters to open up the exhaust path. It is a direct bolt-on solution that integrates with OEM connections and will not trigger a check engine light.
Developed with a flow-optimised layout to reduce backpressure, the Redstar secondary cat delete delivers faster spool, sharper throttle response and a clear increase in power delivery. Lower restriction also helps manage under-bonnet heat, and with Redstar's OEM-style heat shielding option, radiant temperatures can be reduced by up to 80 percent. Expect a stronger, more immediate drive and a deeper, more engaging exhaust tone.
Built for longevity and precision, each assembly uses 2.0 mm wall 304 stainless steel, TIG welded and back purged with OEM-spec V-band flanges and factory-style brackets and mounts. Backed by Redstar performance exhaust expertise, these downpipes provide a durable, hassle-free fit for X5M F95 and X6M F96 owners seeking uncompromised flow, authentic Redstar sound, and true bolt-on installation.
Available Options
- 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. Unlike wraps or coatings that degrade quickly, Redstar shielding delivers long-term durability and consistent protection for engine bay components."
