Big oof. Wonder what parts they used. Amusingly the cheapo o2 sensor I used when I replaced ours after the cat got nicked has just thrown a fault. Probably better to pay what you did rather than the absolute bottom of the barrel parts like I did (and the subsequent headaches).
So my stolen catalytic converter replacement has been sorted - a shade over £1100 and that’s not using any Honda parts. Happy fucking Monday.
