Hi all, ive got a 325 coupe on a K plate, now, i want to remove the catalytic convertors, what i would like to know is, which year was it when they made it law that every car had to have them? as a mate of mine told me that it was 1994, i thought it was earlier than that, i dont want to mess about come every MOT refitting the cats. any ideas? thanks.

I believe it was K reg 1993 but I'm sure Ronniw will confirm this.

Please can you post all your vehicle details in the thread title as per the forum rules:thumbsup

I'm sure it was mid '92 that the law came in...

Im 99% sure cat's were intoduced in 1993 on some late "J" plate cars, so if yours is a "K" then it should have a cat in order to pass an emissions test. Dont quote me on that though!
Didn't see the above post, conflicting information!

My car is a 1992 but didn't legally have to be fitted with one. I believe cats were being used on some vehicles even before this.

Ronnie will put us straight:rofl

what sort of bhp increase should you get if you remove them and put a full stainless on? mines aug 92 on a k (325i) so im going to look into this, maybe race headers would make a difference aswell
