I would definately be interested in the catalytic converter you have going spare for sale. I still need one for my 5exi for it to pass the SVA test as my original donor Rover had one. Will it definately fit on the standard exhaust system on the 1.6 k-series 5exi? £90 seems reasonabl, although I don't really know how much a new one would be?
Yes my donor is newer than 1995 it was manufactured in 1997 so I'm certain i do need a catalytic converter to pass the sva and subsequent mot tests. I haven't had a chance to measure the de-cat pipe that came with the kit but i'm pretty sure it is the standard one for all 5exi exhaust systems. If the cat is still for sale i would like to buy it from you.
