Strange Cat problem??!!

[lundy1543]

Hi Folks, well just changed the Clutch Slave Cylinder on the Cerb, only 6 hours, but what a difference. Whilst i had the Exhausts off i checked the Cats, only to find that the bottom one was completely empty and the top one was in good nick. Any ideas whether i should empty the top one as well, decatting in effect, or will it run ok with one cat and one empty can? I noted that both cat pipes had there own Lambda sensors and i wonder if this will be giving the engine management system some incorrect readings. Also noted that the clutch fitted to the fly wheel had 2 clutch plates?! anyone else seen this?? Thanks in advance. Tim.

I had my Tuscan de-catted and that needed some tuning after it was done.....also those cats are not cheap! You might want to think twice before clearing out the other can. Better to buy a knackered 2nd hand one I would have thought. It will sound even better though!
