Just passing on very usefull info here so the rubbish, guessing and confusion can stop with regard to M.O.T. emissions on the Supra without 'CATS'.
It's very simple, J-spec, N/A or Turbo.
For the import TT's or n/a's there is not a specific application for them in the books and reference manuals for emission test readings.
But there is an alternate chapter for all cars that come under this, so there is NO escape......
Basically here are the hard facts, any *SUPRA* manufactured/registered before "31 JULY 1995" there is a very lapsed emission standard, and basically you CAN PASS an M.O.T. with BOTH CATS OUT!
If your *Supra* was man/reg after "01 AUG 1995", you face the new harder emission tests.......and more than likely will pass with just ONE CAT OUT................
ANyone is free to challenge this, but it's in black and white.
