Decats and MOTs
Discussion
Fellow Jap Fiends, please provide me with some clarification and, ideally, tell me what I want to hear 
What exactly is the deal with decats and MOTs? Firstly, am I correct in that only post 1993 cars need a cat?
And also I was told by someone "in the know" that Jap Imports up to 1995 are exempt?
Would it be wise to post up a "How to bribe MOT testers" thread?

As far as I know...
Regardless of year, if it had one, it must be working. Imports and all.
That said if you don't have one and still get good enough CO figures I've found most places still tick the box.
I always thought it was June 1992 > cars that needed cats.
My GT4 was a Jan 92, and I had it decatted 2 weeks before MOT time, didn't even think about it til afterwards, passed no worries.
Although mine wasn't an exact "de-cat" more of an original cat with the innards bashed out with the handle of a hammer!!!
Is that what you wanted to hear??
edited to say, the bonus of "de-catting" the original is that to an inspector (or anyone else for that matter), it looks standard. Not that I would condone anything of that nature.

Cheers Batty thats just what I was after - although where is the database?
Sir Turbo of Tastic, yeah, I originally was decatted that way, but the replacement downpipe creates a much smoother air flow, resulting in quicker spool up and a few more GGs!

Ahh, I see. I always fancied getting a proper one on the 'Four, would have been nice to see the difference. I have heard people talking about using a dremel to smooth off the inside of the stock cat, but quite how long that would take I dont know.
I also always wanted one of these to go with the downpipie.
