Audi S4 / S5 / SQ5 B9 3.0 TDI V6 De-CAT & EGR Cooler Delete Kit

Audi S4 / S5 / SQ5 B9 3.0 TDI V6 De-CAT & EGR Cooler Delete Kit

EGR Valve & Cooler Delete Kit with De-CAT Exhaust Pipe for Audi S4 / S5 / SQ5 B9 3.0 TDI V6

Our EGR & Cooler Delete with De-CAT Exhaust Removes the Factory Low Pressure and High Pressure EGR Valve / Cooler and Catalytic Converter on Audi S4 / S5 / SQ5 B9 3.0 TDI V6 Diesel Engines.

On these engines such as the DEWA / DEWB found in the diesel S4 / S5, the CAT right after the downpipe feeds two EGR (Exhaust Gas Recirculation) Coolers, one downstream and one upstream.

Our kit is supplied with a De-CAT Exhaust Pipe and all hardware required to remove both EGR coolers and blanking the necessary EGR ports.
