Quite clearly a topic for you crazy BX dudes.
I have posted his e mail below.
Good Luck ,


Hope you guys can help me out with this!
Not many people in the UK have a 16V BX with a cat fitted. Guess I'm lucky (d'oh!), but since my car isn'r required to have a cat fitted for its age ('92) I'd like to ditch it when I get a stainless exhaust made up.

My problem is this - 'cause nobody here has done it I have no idea what the effect would be of removing the cat on the way the car runs. I know I'll need to get the lamda probe tapped into the new exhaust to prevent it over fuelling but will I get the full 160BHP this engine should be capable of without the cat? Mine feels fairly strangled at the moment - I need more!!

Any advice or personal experience welcome
