Product Details

Upgrade your Audi RS6 or RS7 C8 with a premium particulate filter-back exhaust system engineered for performance, sound, and style.

Key Features & Benefits

  • Direct-fit, no cutting required: This system installs directly from the particulate filter back, replacing the OE rear exhaust without the need to cut or modify the factory system. 

  • Twin 80 mm (3.15") piping: Large-diameter dual 80 mm pipes improve exhaust flow significantly over stock, reducing backpressure while retaining strong mid-range torque. 

  • Polished oval dual-tip finish: Stylish polished oval tips provide an aggressive, high-end look — a clean and sporty aesthetic that complements the RS6/RS7 rear fascia. 

  • High-quality construction: Built from aircraft-grade 304-series stainless steel, the exhaust system resists corrosion, discoloration, and wear — ensuring long-term durability and a premium finish.

  • Enhanced exhaust note & driving experience: This exhaust delivers a deeper, more aggressive exhaust tone and sharper throttle response, transforming the driving feel from stock to sporty.
