I believe Librands have now changed to a 400cpi cat which is less likely to cause MOT problems. Mine is the earlier type which has 200cpi and requires to be run up to high temp to pass the emissions test - but it always does on the 2nd or 3rd pass so no worries.
I am interested where the Cat is placed. I have a system where the Cat (200 CPI) is right after the 4/2/1 and sits direct under the sump and have no problems with emission tests. I was advised that this is better as the Cat stays hotter.
