Supersprint front pipes with high flow metallic catalytic converters by HJS Motorsport, Made in Germany http://www.hjs-tuning.de/en/3/105/0/seite_1/Technics/Sport-Catalytic/sport_catalytic.html
On cars fitted with catalytic converters on the front section, these components will replace them, drastically reducing the backpressure and flow restrictions. This allows better performance but at the same time optimal pollutant gas reduction thanks to the high quantity of noble metals.
On cars where the catalytic converters and secondary sensor bungs are placed in the manifold, these components are recommended for use in conjunction with the Supersprint headers. The headers replace the OEM item (manifold with pre-cats) with a much more free-flowing long tube manifold. The Supersprint metallic cats reduce the pollutant gas. Periodic emission tests can be passed, there's no smell and extending the sensor wires and plugging the sensor after the new sports cats there won't be any Check Engine Light issue.
Must be fitted with the Supersprint center section, the outlets don't align correctly with the OEM part.
