Hi Kyle, that's interesting as I heard from someone today that late model Falcon cats have had success. XF Falcon is mid 1980s - are you sure about the model?

Thanks for the offer of the laser temp gun. What temp rise are we expecting between front and back of the cat? I think for this trial and error kind of exercise I'll rely on the 5 gas analyser test, which is only about $100 worth of dyno time and should tell me whether I'm going to pass the IM240 - or not, so I can avoid the sting.
