Audi S4 B9 3.0T 2017+ – Exhaust Decat Downpipe

Decat Exhaust Downpipes are manufactured from T304 grade stainless steel, and feature a heat shield to give extra heat protection on those intense track-sessions.

A direct replacement for the stock part, mandrel-bent exhaust components are fully TIG welded and feature CNC-machined flanges for strength and an accurate, secure fit every time.

Engineered to not only improve power and torque across the entire RPM range but exhaust components improve throttle response to help you push further and faster on the road or the track
