headers and cats.. help

[the barber]

So yesterday I decided to do my rear cat removal, my self, needless to say I should have waited for an experienced welder. Long story short F'd up the welds and had a buddy re-weld them no leaks and now I do believe I have a leak where the header and cat connect and have been looking for the gasket or something to fix this problem does n e one have n e insight on-the-job part I'm looking for or a solution? Thanks in advance Alex.

If you need the gasket here is a link for the LS3. #2 left or right is on this page.

Not sure if same gasket for L99 but pretty sure it is. So just search the site under the auto exhaust if need be.

I assume you removed the cats from the manifolds to do this job. Maybe didn't tighten down enough when you put back together? These are metal gaskets and just like the manifold gaskets should be good for at least another use after removal as long as you didn't damage them.

In hindsight it probably would have been easier to have just gutted the rear cats rather than cut them off as they aren't that deep into the pipe.
