Ive just purchased a decat up&down pipe, but im leaving the rear cat on-will i need the cel fix(from scoobysport) or not???

 

If you are thinking of having the car re-mapped by EcuTek after de-cat they can "map out" the missing cat problem in the ECU without the CEL fix.
I have a CEL fix from Scoobysport which isn't 100% effective.
