Like this Bull-X Downpipe / DPF replacement pipe for Audi A6 4F 2.7TDI and 3.0TDI.

You want to get more power and sound out of your TDI?
Then you should start with a Bull-X product!

Downpipes are a significant part for torque range and power in a turbocharged system. It´s the connection between the turbocharger and your catback exhaust. As bigger the diameter of the downpipe and as lower the exhaust gas back pressure, as easier and quicker the turbocharger is able to lead off the exhaust gases.

This has a positive influence in torque, sound and power. Another good aspect of this product is, that its suitable for AWD and FWD models. Because of the removal of your DPF and catalyst, an ECU remapping will definitely be required.

The advantages at a glance:
• Made of stainless steel
• Because of our multi flange, this product is suitable for facelift and pre-facelift models
• The turbocharger is able to lead off the exhaust gas easier, this is the reason for more power
• Better torque range, because the charger can work faster
• Lower exhaust temperature, so the charger and the exhaust manifold is more protected
• OEM connections for plug and play installation
• Suitable for all Quattro and FWD models, incl. Facelift

After installation, the adaptation of the motor control is absolutely necessary!

The probe connections are missing from this product..

Note: For modelyear 20042005 there are some 2.7 / 3.0 TDI models, which are factory-fitted without DPF and instead have 2 Oxikats installed. For these models the DPF replacement pipe doesn´t fit.
The Bull-X downpipe/catalyste replacement pipe fits at all models. In order to reduce the exhaust gas temperature even higher for higher power increases and to fully exploit the Soundplus (in combination with a modified exhaust system), we recommend the installation of the complete downpipe.
