A small update. I put the lude in for an MOT the other day, it sailed through. The only advisory was a slight blow from the flexi pipe (which I knew about).
A few weeks ago I gave it a service:
I've been having a headache with my exhaust lately too, I bought a Honda Access back box from Mills a few months ago, I recently also bought a new centre section. It was a massive ball ache to remove the old exhaust, had to angle grind the nuts off, drill out the studs etc...
Anyway, fitted the new centre section and Access back box.... To find it was 4" too short. Turns out the JDM cats are shorter.
So I think I may have a custom stainless centre section made up. On a plus note, the Honda Access backbox looks awesome when fitted. I forgot to get a picture though lol :/
