I'm thinking 12-16 hours.. This was done at Bills shop at his convenience over the course of two or three weekends.
It was all done by me, when I got jammed up, Bill showed me the way.
It took half a day to remove the old system.. All six of the header/muffler studs had to be burned off..
I've had pretty good luck with my 911's inre exhaust and muffler work, if I could see the future and see that 8 of 12 bolts would break ( f/u Porsche) I would have skipped the heating to cherry red non sense.. and just broke the bolts, and dove into drilling..
I then got carried away cutting the broken studs, so didn't want to have to drill anymore than I had too.. So I cut a good reference away
Fixture located with pins and the "close" stud we drilled..
Note to users: drill close to where the fixture is fastened, it can walk if drilled at opposite end
Pretty corrosion resistant studs
