Front Metallic catalytic converter.

Supersprint front pipe with high flow metallic cat by HJS  Motorsport, Made in Germany http://www.hjs-tuning.de/en/3/105/0/seite_1/Technics/Sport-Catalytic/sport_catalytic.html

This component is designed to be fitted with the turbo downpipe 768911.
As the original catalytic converter palced close to the turbocharger is removed, this results in a catless exhaust system, with the typical smell and not compliant with the pollution regulations in many countries.

Fitting the Supersprint front pipe with sports cat the pollutant gas will be reduced efficiently.
The different position, under the frame instead of inside the engine bay, is also good for performance and for temperature, as the cat can exchange heat with the air flow instead of soaking the engine bay with it.

It's necessary to extend the secondary O2 sensor wire to be able to plug it in the bung after the new cat, unless the sensor itself is turned off by ECU tuning or cheated with an emulator / microcat.

The HJS metallic cats are the best on the market, with the highest concentration of noble metal, with the best pollutant gas reduction and performance gains.

To be able to fit this part with the OEM centre pipe the outlet diameter must reduced from 60 to 55mm.
Please specify this when you order the part.
