BULL-X Exhausts produces Downpipes at the highest level.

Like this 3" downpipe for Audi S3 8L 210/225HP and Audi TT 8N 225HP models.

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

The downpipe is a significant part for torque range and power in a turbo system. The downpipe is the connection between the turbocharger and the catback exhaust. The bigger the diameter of the downpipe, the easier and quicker the turbocharger is able to lead off the exhaust gas. This has a positive influence in torque and power.
If the engine warning light comes on after installation, the ECU software must be adjusted.

The advantages at a glance:
• 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
• optional available with 200 cells sport catalyst

Catalyst information

When selecting a downpipe without a catalytic converter or with a 100/200-cell catalytic converter, there may be an error message of the post-catalytic lambda sensor in the control unit, which does not lead to restrictions in driving operation because the first lambda sensor end is present for the motor control. The post-cat Sensor is only responsible for monitoring the effect of the catalyst. This can be programmed out by adapting the software from a chip tuner.

With most cars up to Euro 3 Emission code, there is no post-cat Sensor and installation is possible without further adjustment and error message.

The wash coat content of HJS ECE and EOBD Kats is significantly higher and is characterized by a very high oxygen storage capacity, which means that errors can be avoided. The EOBD Kats are tested for this topic up to Euro 4. The durability and the use up to the Euro 6 exhaust-gas standard is of course given.
For Euro 5/6 vehicles, the above points can only be avoided if a cat with an ECE selection is made.
