Damn you guys... "Can't you just weld..." I feel so inadequate.
One of these days I'm going to have to get a welder and teach myself to use it. They're so expensive though....where do you start? A buddy of mine left a little 90A stick welder at my house, and that thing is a joke. I can burn holes in stuff, but that's about it.
Yeah, it does look like maybe you could weld something over the hole. I assume on this one I have to pull the engine to get the exhaust out, right?
Oh, and Jaybone, thanks, but it's a 90, not a 70. If you search ATC90 exhaust (at least in the last few days) you get one hit, and there's no way I'm paying $135 for a muffler that's as rusty as the one I've already got!
