exhaust leak
I have a 1997 f150 4.6L.
There's been a quiet ticking coming from somewhere in my exhaust system(stock with a cherry bomb replacing the muffler) for a month or two. I finally got sick of it & diagnosed the problem. It appeared to be a hole in the catalytic converter & after some thinking, I decided I don't want to buy a new one, so I'll just replace them with dual pipes all the way back. I torched the pipes off before the converters & started the truck (now sounds like grave digger). Only problem now, the ticking is still there. I just had the manifolds replaced last spring, so there's no way they should have a hole in them.
Question is this: is there anything else that could be causing the ticking? Today it started flashing the check engine light for a misfire, but I've had a misfire before & it didnt tick like this does.
Any help or guesses are appreciated. Sorry if this post is somewhere else, I'm on my phone & this isn't the easiest site to navigate without a computee

Torched off converters now check engine light duh. must be a hell of a tick if you can hear it above an open exhaust

the tick isn't just an average manifold-sounding tick. it sounds like it's coming out of the end of the exhaust pipe itself. Like if there was an internal tick somewhere & the sound traveled through the pipe & out the end. I have no idea what it could be.

It's possible that the ball-in-cup connection at the manifold is loose. I always tighten those things up again after they've heated and cooled a few times. Just try and tighten it at the flange where these flange bolts are.

that's a very good possibility. I will definitely check that. thanks!
