Unleash a richer Redstar sound and response from your Audi RSQ8, RSQ8 Performance, SQ7, SQ8, Bentley Bentayga 4.0 V8, and Porsche Cayenne S 4.0, Cayenne Turbo 9Y0, and Cayenne Turbo GTS 9Y0 with the Redstar Exhaust Resonator Delete. This performance exhaust upgrade replaces the front resonator pipe immediately after the downpipes with a direct, plug-and-play section. Installation is fully bolt-on with no cutting required and no check engine light issues. Bentayga note - only fits the 4.0 V8, not the W12.

By removing the factory resonator in the section after the downpipes, this Redstar system frees exhaust flow to deliver significant power gains, faster turbo spool, and sharper throttle response. The result is a deeper, more complete and aggressive exhaust tone across these 4.0L twin-turbocharged V8 applications - with a sportier growl that is more assertive than the Lamborghini Urus.

Precision built for OEM-like fitment, each Redstar resonator delete uses 2.0mm wall 304 stainless steel, is 100% TIG welded and back purged, and features OEM-spec flanges with factory-style brackets and mounts. Optional OEM-style heat shielding reduces radiant heat by up to 80% to help protect surrounding components. Choose Redstar for a seamless performance exhaust upgrade that integrates cleanly with your factory system.

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.
