Unleash your Bentley Bentayga 6.0L W12 with RedstarÕs Secondary Cat Delete - a precision upgrade for the Bentayga and Bentayga Speed that replaces the secondary downpipe section after the primary downpipes. This plug-and-play solution is engineered for clean integration with the factory system, with no cutting required and no check engine light issues. Designed specifically for the W12 6.0 - does not fit the 4.0 V8.

By removing the restrictive secondary catalysts, this secondary cat delete improves exhaust flow for significant power gains, faster spool-up and sharper throttle response, while adding a richer, more characterful exhaust tone. Optional double-layer thermal protection targets under-bonnet temperatures, with integrated insulation reducing surface temperature by up to 70% to help safeguard nearby components and support consistent performance.

Built for longevity as well as performance, each Redstar performance exhaust component is crafted from 2.0mm wall 304 stainless steel, 100% TIG welded and back purged, and finished with OEM-spec flanges and factory-style brackets and mounts for a true bolt-on fit. If you are seeking a high-quality downpipes solution from Redstar that enhances drivability and sound without compromising fitment, this secondary cat delete is the ideal upgrade for your Bentley Bentayga W12.

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."
