The catalytic converter in my 1991 Volvo 240 is rattling like crazy at about
2400 rpm. It's just been through its MOT and I noticed it was tested as a
'uncatalysed vehicle'. If I remove the cat, replacing it with the old
fashioned centre exhaust section and silencer, would I be breaking any laws?

The only online resource I have (http://www.ukmot.com/manual/appendixB.htm)
doesn't really specify.

Thanks,

Dave

P.S. I know the Volvo is hardly classic yet, but it's all I have when the
Triumph sleeps in the winter.
