3" High Flow De-Cat Downpipe for Audi SQ5 / A6 / A7 V6 3.0 Bi-Turbo TDI

3" High Flow De-Cat Downpipe for Audi SQ5 / A6 / A7 V6 3.0 Bi-Turbo TDI

316L Stainless Steel 3" High Flow De-Cat Exhaust Downpipe for Audi SQ5 / A6 / A7 V6 3.0 Bi-Turbo TDI Diesel Engines

Our 3" De-Cat Downpipe has been designed and manufactured to be a direct replacement to remove the factory Catalytic Converter (CAT) on the 3.0 V6 Bi-Turbo TDI Vehicles.

We have designed this downpipe with exhaust flow in mind, the 3" diameter and our new CNC machined stainless steel flange all benefit the engine with power in mind.

Traditionally we would opt to use a 12mm stainless steel flange to adapt to the 3" tube however due to the complex shape of the Bi-Turbo models this can sacrifice flow. Using our new CAD developed flange we can offer maximum flow

When buying the De-Cat downpipe you may require a custom ECU Remap to erase any fault codes or engine management lights. We will not be responsible for any problems that may occur with any other tuners software

Our DPF Delete Pipes are supplied with only a Lambda Sensor Boss. The Pre-Turbo EGT Boss is located in the Exhaust Manifold on the Turbocharger. All other EGT and Pressure Sensors are not required when removing the DPF, leaving them in the downpipe can eventually lead to sensor failure, creating a fault in the ECU and possibly a Check Engine Light in the Instrument Cluster. With the correct DPF Delete Software, these sensors are removed entirely so they can be unplugged and removed from the car. If your tuner cannot remove these faults, the sensors should be left plugged in and wrapped out of the way
