Which 4? the headpipe to CATs? or the CATS to the 2nd (merged) CAT?

I just snap the bolts off the 2nd CAT. They are cheap and easy to replace. I'm only 5'7".

The nuts on the head pipes, I bet you could get a nut cracker on them. If not, get out the dremmel and cut a groove. It doesn't have to go all the way through. It'll come off.

Transmission R&R is 4.5 hours by the book rate. The transfer case R&R takes me 5 hours in my garage.

SVX looks good up on jackstands, eh? I love my "BONE" creeper for SVX work. HIGHLY recommend it.
