Bull-X 2.75″ downpipe with catalytic converter and DPF replacement pipe for Audi A6 C6 2.7–3.0 TDI

Would you like to achieve more power from your TDI while reducing the load on the turbocharger? Then a Bull-X downpipe is an excellent place to start. The downpipe has a significant effect on response and power. It forms the link between the turbocharger and the exhaust system. The larger the pipe diameter and the better the flow, the more easily the turbocharger can discharge the processed exhaust gases through the exhaust system. This has a positive effect on torque, power and the engine sound, particularly when combined with a modified exhaust system.

The upper section of the downpipe has a connection for a lambda sensor.

Note:

1. The engine control unit must be recalibrated after installation.
2. Some 2.7/3.0 TDI models from model years 2004/2005 were factory-built without a DPF and instead fitted with 2 oxidation catalytic converters. The DPF replacement pipe does not fit these models.

Advantages

• The turbocharger can discharge the exhaust gases more easily, resulting in increased power.
• More torque, as the turbocharger reaches operating speed more quickly and is subjected to less resistance.
• Lower exhaust gas temperatures, reducing the load on the exhaust manifold and turbocharger.
• Direct installation thanks to the OEM-style connections.
• Suitable for all quattro and front-wheel-drive versions, including facelift models.
• Manufactured from stainless steel.
