Vauxhall Astra Mk4 GSi, Coupe Turbo De-Cat Exhaust Pipe



Vauxhall Astra Mk4 GSi, Coupe Turbo De-Cat Exhaust Pipe. This aluminised mild-steel de-cat is a direct replacement for the original Catalytic Converter on all Astra Mk4 petrol Turbo engined models. It fits directly to the three bolt flange at the bottom of the'pre-cat' pipe (which is retained), and directly onto a standard or performance exhaust centre section. The second lambda position is provided. The engine feels ultra responsive and more willing to zip through the rev-range with this De-Cat fitted. NOTE: This item was developed for Competition and'Track day' use and is NOT M. The ECU light may remain'on' with this De-cat fitted.
