Test pipes install, fail. Opinions and advice please!

[shika805]

So this past weekend I installed my new ark grip v2 exhaust. I have to say it was a simple install with not much hassle. I'm paring the exhaust with some cnt resonated test pipes. I thought I might as well get them done while installing my exhaust.

I've read a lot of threads from past experiences with the dreaded bolt that is inaccessible under the car. I went through the intake, through the engine bay to by pass the bolt (what people have done). The bolt did not budge at all. We tried so hard that we ended up striping the bolt. I even had the bolts sprayed with penetrating oil the night before and still no go. I didn't try to attempt the other side.

Now my question is, what are my options? Somehow get a grinder in there and cut the bolt? I don't want to damage my headers and cats, I want to be able to switch the cats come smog time.

Any help with this much appreciated. Thanks in advance.
