I also recently did an oil change, with the level to the maximum.

My manifolds are cracked and a recent long battle with a dead misfire might’ve clogged the rear cats with raw petrol, as the pop came just after the primary cat.

I might try a liberal application of wire, exhaust bandage, and exhaust putty to seal the hole up temporarily to see if the stumbling problem reappears before committing to a new exhaust section. Don’t want to fit a new one and then have it burst straight away again.
