CEL light code Catalytic conv - Question

Hi folks, Well I was out in Inverness with the good lady 2 weeks ago and during an exceptionally wet day driving along the road into town the CEL light came on, the car seemed fine, made no noticeable hesitations etc. So I did the dance of a thousand pedals and got P0430 as a code. A bit of googling over a costa found that this was an issue with the catalytic convertor. Once I had got the code the light had gone out, but came back the other day, it threw up the same code, again I can notice no difference in running of the car, fuel efficiency etc (car always run on super 98\99). I have a Borla exhaust and hi flow cats on the car, and I kow aftermarket exhausts can cause this issue but I wondered if it was a screw in sensor or some such that could be on the way out, or is this simply something that occurs due to aftermarket cts? though I have run the car for about 2 months before this started. Any info or advice would be great, as I am about to do an oil change and knowing if there are any areas I should be looking at under the car would be grand. Cheers all. (apologies for wall of text, but return function isn't working in text box???)
