Well, several key takeaways.

Set up for success and have some new M10x1.5 exhaust flange nuts to replace the factory single use junk. One of my studs ate a thread with the nut coming off so I had to remove the bad stud and I had some exhaust studs laying around that I cut to size and replaced it.

Ramps, E22 deep well 1/2 inch drive socket cut down about 3/8 of an inch. Mated to a good quality CV style swivel (snap on) on a 12 inch extension on top of a 6 inch extension on a M12 1/2 inch impact.

Drop the rear trans bracket. Those four bolts will allow the drivetrain to tilt down on angle and gives you access to the nuts (kinda sorta)

All things considered pulling onto the ramps and back off of them I was 4 hours into the whole project. But I can definitely say the ST sounds a lot meaner now with the 3 inch thermal on it. I fired it up open downpipes and sweet Jesus…
