Just a quick question, do early MX5s have catalytic converters?
Yes, though decat (straight through exhaust et al) is a common mod. Cats can be legally removed from all cars (in the sense that you can pass an MOT without one) if the car was originally registered before late 1992, I think - anyone know the exact date?
On particularly old cars the cat may well be there, but may not be in great nick after 2 decades, so if you have one do keep an eye on it.
