Description
HJS ECE R103 type-approved tuning catalysts are developed on the basis of Motorsport catalysts.
HJS cones are designed to optimise exhaust gas flow into the catalytic converter, resulting in increased performance and lower exhaust pressures in the so-called 'afterburner' catalytic converter.
compared to the basic covers.
Note!
ECE type approval is only valid when both primary and secondary catalytic converters are installed at the same time.
The installation must be carried out in place of the original catalytic converters.
See the table in the product description for compatibility with the car model.
