BULL-X Exhausts produces Downpipes at the highest level.

The Downpipe for Audi RS3 400HP with OPF and TTRS 8S 400HP with OPF of HG-Motorsport can be exchanged at 100% for the standard part. Perfect fit and high quality material make this product a top product from our range. By optimizing the diameter, piping and / or catalyst of the turbocharger can be greatly relieved.
A lower back pressure and thermal relief generate a significant increase in torque, power, previous response and the same time an extension of the shelf life.

- Stainless steel
- optionally with cat replacement pipe, incl. 2x100 cells sports catalyst, incl. 2x200 cells sports catalyst, with Bull-X 2x200 cells EOBD sports catalyst by HJS
- without approval

Advantages in an overview:
- Stainless steel
- Plug'n'Play solution - perfect fit can be simply exchanged for the original part
- High-quality materials
- Made in Germany - real quality from our own production
- Flow-optimized and performance-enhancing
- Improvement of durability and response
- Optimum removal of exhaust gases - without disturbing edges at the transitions
- Designed and tested on the PC and dynamometer

When installing this downpipe, a software adjustment is necessary.
The temperature sensors and the differential pressure sensors must be deprogrammed.
The downpipe is delivered without connections for these sensors to avoid unnecessary costs.
With our software solution, however, the differential pressure sensors remain installed in the vehicle and are simply connected to each other in a loop (both hoses of the sensors are simply plugged into each other, as the tolerance value is reprogrammed here).




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.
