Wagner Tuning Downpipe Kit Audi S4 (B9)

Wagner Tuning 300CPSI EU6 Downpipe Kit - Audi S4 (B9)

Wagner Tuning builds this downpipe kit in Germany using CAD designed, flow optimised stainless steel construction, aimed at reducing turbo back pressure and unlocking more of the 3.0 TFSI's potential. It's a direct OEM replacement for the Audi S4 (B9), engineered to drop straight in with no cutting or fabrication.

This listing covers the Audi S4 B9 (8W) and Audi S5 F5 3.0 TFSI models, both sharing the same downpipe architecture. SKU 500001031. An optional Ø76mm middle silencer-replacement pipe is also available separately for a sportier, deeper tone.

Note: Fitting this downpipe can trigger an error display in the DME. Wagner Tuning recommends a supporting ECU tune to properly integrate the kit and avoid fault codes.
