Can this be done? Don't really want to fork out for a sports cat just before Christmas, but want to lower my EGT's for Stage 2.
I have spoken to nige at BCS a few weeks ago.
They can supply you a 3" downpipe with what ever cat you want with a reducer to connect to the standed system.
I have also spoken to r-tech about mapping and they said that will be ok.
Should see good results, with out the cost of a full system.
