Redstar Downpipe and Resonator Delete System for Audi A6 / A7 55 TFSI (C8)

Redstar's performance downpipe for the Audi A6 / A7 (C8) replaces the factory downpipe on the 55 TFSI 3.0 litre turbo engine. It suits the 2019-on A6 sedan and Allroad and the 2018-on A7 Sportback, including the C8.5 update, in both right- and left-hand drive. Redstar builds it as a bolt-on replacement with OEM-spec V-band flanges and factory-style brackets and mounts, aiming for faster spool, sharper throttle response, lower under-bonnet temperatures and an improved exhaust tone than the stock part.
