(2001 S) Hey guys, bought some exhaust parts off eBay and they came with a little surprise. The original bolts were cut on one end but they seem to be word welded on in the other end. And I can't reuse them because they're half size so I HAVE to remove them. I've searched on the forums and I've seen talks about just cutting the head off and they fall off but I've also seen talks of some bolts being pressed in. Here's what I have so far and what the other bolt that I haven't gotten around to yet looks like. What do I need to do? I've cut off the head and grinded the side down but I still can't hammer it out.
