  • Question about this product?

Would you like to achieve higher performance with your turbocharged engine and at the same time relieve your turbocharger and protect the surrounding components?

Then you should start with this Bull-X product!

This downpipe with a diameter of 2.75"/70mm is significantly involved in the points of pull and performance. It is the link between the exhaust side of the turbocharger and the exhaust system. The larger the pipe diameter, the easier it is for the turbocharger to discharge the processed exhaust gases through the exhaust system. This has a positive effect on torque and power.

The advantages ata glance:
• lower exhaust
• gas temperature, which relieves manifolds & chargers
• the turbocharger can dissipation the exhaust gases more easily, resulting in more power
• more torque, as the charger reaches speed faster and is not braked
• Soundplus

Catalytic converter information

Whenselecting a downpipe without cat or with 100/200 cells cat, there may be an error message from the Nachkat lambda sensor in the control unit, which does not lead to restrictions in driving mode, since the first lambda sensor for the engine control is present. The post-cat probe is only responsible for monitoring the cat effect. This can be programmed out by adapting the software from a chip tuner.

For most vehicles up to Euro 3 emission standard, there is no aftercat probe and installation is possible without further adaptation and error message.

The washcoat content of HJS ECE and EOBD Kats is significantly higher and is characterized by a very high oxygen storage capacity, which avoids error messages. The EOBD Kats are tested for this topic up to Euro 4. Of course, the durability and use up to the Euro 6 emission standard is given.

For Euro 5/6 vehicles, the above points can only be avoided if a cat is made with an ECE selection.
