Have had a my99 impreza for a couple of months and quite satisfied and am starting to do odd performance bits to improve.Will a de-cat downpipe make much difference and be a worthwhile investment,what price do they sell at?
Have a Scoobysport back box on it when purchased.Secondary,how bad are they to fix as when I looked underneath on a routine check it seems these areas take all the salt and water and have visions of shearing nuts.Cheers
