Installing catless downpipes will require ECU adjustment to remove the CEL for catalyst efficiency.
QuickSilver Catted Downpipes are also recommended to be installed in connection with an ECU tune. Whilst the cat may run cleanly and pass an emissions inspection, the ECU’s downstream o2 sensor may detect a flow and light up reading outside of it’s prescribed parameter.
In short, if you’ve fitted a QuickSilver downpipe, and have a CEL for catalyst efficiency, please contact your local authorised dealer or specialist tuner.
QuickSilver Heritage Systems are drafted from original, OEM patterns.
Classic cars, particularly British & Italian hand-built marques require the exhaust tailoring to each vehicle – this work must be undertaken by an experienced classic car specialist or approved QuickSilver heritage dealer.
Please note that QuickSilver do not have the tooling to produce specific classic clamps, composite gaskets or rubbers – and these must be sourced separately.
