I had a fully decatted exhaust on the car when i bought it (complete with the standard exhaust for mot time) but the 1st time i got it mot'd an swapped over my local mechanic suggested i leave at least the front cat on so i did an its been on for 2 yrs now.
Was just thinkin what will i gain from fully decatting it?
Its a 2000 uk turbo.

mine is the same only 1 cat removed was told that removing both would get me about 10bhp more
not sure how true that is mind

I think you need to get it mapped to really notice the difference and believe me if you did you will notice it big time i did lol .
