Bull-X Exhausts produces exhaust systems and downpipes at the highest level.

Like this Downpipe for Audi A4 B8 + Audi A5 B8 2.7-3.0 TDI models.

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.

To mount this downpipe on a pre-facelift model, you just have to cut off a small piece of our multi flange (marked on picture 3).

An adaptation of the engine control is mandatory after assembly!

The advantages at a glance:
• 3" pipe diamter
• 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

Note: This is the short version. (Most vehicles have this type installed)
Please check your original part before ordering. (If your downpipe is longer at the point where the lower flange sits, this DP does not fit in your vehicle or only with adaptation work.)
