I have just got a quote to have a performance stainless steel exhaust fitted to my vehicle.This is for the 'full' down pipe back system and totally does away with the 'cats'.What I was wondering is will my vehicle 'pass' the UK MOT test without them (it is a March '92 model/registered and 'cats' have to be 'used' after Nov '92)Mainly a question to the UK bunch !Also what power gains would I be likely to see?[
