Take your Audi RS4 or RS5 to the next level with our high-performance downpipes engineered specifically for the B9 and B9.5 platforms. Designed to maximize exhaust flow, improve turbo efficiency, and enhance engine performance, these downpipes deliver the sound and power your 2.9L Twin Turbo V6 was built to produce.
Constructed from premium T304 stainless steel and designed for direct-fit installation, these downpipes provide a significant performance upgrade while maintaining excellent fitment and long-term durability.
Increase Power & Turbo Performance
Factory downpipes can create exhaust restrictions that limit the full potential of the 2.9L TFSI engine. Our performance downpipes are engineered to reduce backpressure and improve exhaust flow, allowing the turbochargers to operate more efficiently.
The result is improved horsepower, stronger torque delivery, faster turbo spool, and enhanced throttle response throughout the RPM range.
Aggressive Audi RS Exhaust Sound
One of the most noticeable benefits of upgrading your downpipes is the dramatic improvement in exhaust tone.
Experience a deeper, louder, and more aggressive exhaust note that fully complements the character of Audi's twin-turbo V6 while delivering the signature RS sound enthusiasts love.
Premium T304 Stainless Steel Construction
Manufactured from high-quality T304 stainless steel, these downpipes are built to withstand extreme temperatures and harsh driving conditions.
Each unit features precision TIG welding to ensure maximum strength, durability, and leak-free performance for years of reliable use.
