Has anyone done this?

2 important questions;
How are your emissions on MOTs since, close pass or comfortable?
Did you get any noticable power gains?

Is it a Turbo?
I know a couple of people with Turboed 3SGTE's (Be it in a celica shell, mind) Who managed to pass MOT with a decat. It was probably by either fluke, or under fueling mind. I'm sure on an N/A the emissions wouldn't change much, but then again probably the power wouldn't either? hehe

I read that is was a requirement for the US market only, but not for over here. Pre-cats can fail and destroy the piston rings/piston/cylinder whatever, so could to remove them anyway, even better if you get something more out of it than peace of mind.
