Key Features:

This allows the 4.0T twin-turbo engine to breathe easier, translating to improved horsepower, faster throttle response, and increased torque throughout the RPM range.
-
Free Flowing Exhaust Path: With larger diameter piping and optimized bends, these downpipes ensure minimal restriction and maximum exhaust gas evacuation, leading to better turbo spool times and more efficient power delivery.
-
Premium Stainless Steel Construction: Crafted from high-quality stainless steel, these downpipes are built to endure extreme temperatures and resist corrosion, ensuring long-lasting performance even under the most demanding driving conditions.
-
Integrated Heat Shield: The built-in heat shield provides vital protection for surrounding components from the high temperatures generated by the exhaust system. It helps to prevent heat soak and ensures the downpipes and surrounding areas remain safe and durable.
-
Enhanced Exhaust Sound: By removing the restrictive factory catalytic converters, these downpipes create a more aggressive exhaust tone that lets the Audi RS6/RS7’s V8 twin-turbo engine truly sing. Expect a deep, throaty growl under hard acceleration and a more exhilarating driving experience.
-
Increased Horsepower and Torque: By optimizing exhaust flow, these downpipes unlock significant power gains, making your Audi RS6/RS7 even more responsive, with noticeable increases in both low-end and top-end performance.
-
Direct Fitment: Designed for a seamless, bolt-on installation, these downpipes are a direct replacement for the stock parts, allowing for a hassle-free upgrade with no additional modifications required.
-
Track-Ready and Street Legal (in most regions): While designed to improve performance and sound, please check local regulations regarding emissions as catless downpipes may not be street legal in all areas.
