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?[:)]

Quite a nice sound and a deal more on the aceleration.. I have not done it with my S600 but I did with my A610 Alpine.. the dyno readind was up 38BHP just by putting a pussy pipe in
