Description

Unleash the full performance potential of your Audi, Porsche, or Bentley V8 biturbo with Redstar performance exhaust downpipes and resonator delete. Designed for models including the Audi SQ7, SQ8, RSQ8, Porsche Cayenne S, Cayenne Turbo, Cayenne Turbo GTS, and Bentley Bentayga 4.0L twin-turbocharged V8, this system replaces the restrictive OEM catalytic converters and front resonator to dramatically improve exhaust flow and efficiency.

Engineered using advanced CAD design and flow bench testing, Redstar downpipes deliver significant gains in power, throttle response, and turbo spool. When paired with an ECU tune, these downpipes support extensive power upgrades, including big-turbo conversions, and are rated to handle over 1000hp. Motorsport-inspired heat shielding reduces underbonnet temperatures by up to 80 percent, protecting sensitive components and ensuring consistent performance even under extreme conditions.

Manufactured from premium 2.0mm wall 304 stainless steel with precision TIG welding and OEM-spec flanges, Redstar downpipes offer a true bolt-on installation and a refined, aggressive exhaust note. Trust Redstar for proven engineering, durability, and the ultimate in performance exhaust technology for your high-performance SUV.
