Read evidence and context
Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Suggestion
Have you tried using an air hammer socket adapter?
Leading evidence: 'Use air hammer socket adapter' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Use air hammer socket adapter' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I have noticed a slight exhaust leak for a while. I finally tracked it down, to what looks like is a break at the flange on the exhaust manifold, where it meets the cat.. What is the best way to fix?
I am sure if I try to remove the exhaust manifold, and replace it, I am almost certain to break some bolts off. Car has 100k+ miles on it.
Can this be welded led from the outside of the flange?
Position at rest.
If I flex the cat a little, a gap opens up.
Phil from Fabspeed here.
You should be able to weld that. I would check the the parts before you spend the money to weld them just to have them break again or fail while welding or soon after.
A trick to take the bolts out is to heat them up before trying to take them out.
That can be welded easily. Clean up the pipe and bracket plate with a wire wheel and have someone MIG or TIG it. Drop it from the car and I'm sure you could find a welder that would do it if you bought them lunch.
I agree with you Billup in theory. Just please check the integrity of the pipe as well if it rusted through there that is probably not the only weak part.

Thanks for the feedback. The car came with an aftermarket exhaust, and I have a feeling it caused some stress in the exhaust, when they bolted it on. The pipes are solid, and the break shows when I apply pressure upwards on the catalytic converter.
As far applying heat to rusted bolts on exhaust manifolds, I must be doing something wrong. EVERYTIME I try that, I still end up snapping them off. I try and be soooo very careful, but it usually ends up with me letting some very colorful words fly!
