Hmmm $50 for a second-hand manifold, up to $50 for a new set of studs and a gasket.
The worst part would be labour really, at least a couple of hours to strip and remove the head... maybe an hour cleaning up the gasket face, half an hour cleaning and prepping the head and block surfaces and another hour or so for reassembly.
It's not going to get any worse in a hurry, and as it's not flooding the engine bay with fumes it's not a problem for a wof.
Besides... the sound of all the car alarms the regular exhaust note sets off will drown out the ticking
It's not actually loud, but its a
very deep note... Someone's comment on how deep it was and how it related to parts of the male anatomy are the reason there's a big old black ballbag swinging from the back
