Ok so another fail with with the demon bolt. I didn't try the torch or dremel because I wanted to try with out and i was running out of day light. The bolt extractors gave me a really good bite on the bolt but the bolt extractor began to get dull and it started slipping.
I think I'm gonna have to give up on this and take it to a muffler shop to work on this bolt.
Here are a couple pics of what I did this afternoon.
You can see the bolt now is pretty stripped.
I took off the pasenger intake to gain more access, didn't do much.
I know some people are unclear about what bolt it is. It can be any of the 3 on each cat. My demon bolt is the top corner, most difficult to access.
