Bull-X Downpipe 3,5" Polo 6C GTI/ Ibiza Cupra 6P 1.8 TSI, Audi A1 1.4 TFSI (with ECE*)

BULL-X Exhausts produces downpipes at the highest level.

Like the 3,5"/89mm Bull-X Downpipe VW Polo 6R/6C GTI, Audi A1 1.8TFSI and Seat Ibiza Cupra 6P.

The downpipe is perfectly suitable for both standard and performance-enhanced vehicles.

The installation of this downpipe also leads to an increase in performance as well as an improvement of the response behaviour.
Another decisive aspect for the purchase of this downpipe is that the exhaust gas temperatures are reduced and the exhaust manifold and the turbocharger are relieved.

The advantages at a glance:
- performance enhancing
- Relief of the components
- Plug & Play
- pipe diameter 89mm/3.5" at the turbocharger, further manufactured with 3"/76mm pipe diameter
- *optionally without cat, incl. 100-cell sports cat, incl. 200-cell sports cat, with Bull-X 200-cell EOBD sports cat by HJS or with 200-cell HJS sports cat incl. ECE type approval
- TIG welded
- material: stainless steel
- incl. stainless steel reducer for easy mounting on the standard exhaust system or a connecting sleeve with 76mm inner diameter for mounting on a 3" exhaust system. (optional)

Note: For vehicles with manual transmission, we recommend the use of the reinforced torque arm, as the original bearings deflect very quickly and otherwise contacts/noise can occur due to the larger tube diameter.

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.
