this looks like fun Posts: 3,995 Group: Members Member #2,052 Joined: December 21, 2007	is the cat not just fitted to the later 190's so why not replace the whole pipe from an earlier car

Hi you should get yourself a spare down pipe from the dismantlers and decat that and keep your own down pipes safe, just in case you need to put them back, even if its just to pass the MOT...if you know what i mean!!!! mazza

Hi not really mate!! you just need to weld a connecting flange plate between the down pipe and the CAT. measure up a straight pipe to the same size and weld connecting flanges, easy removal!. mazza
