Well I did make a little progress although nothing like I expected. Stainless just cuts really slow and is hard to work with. I always forget that until I mess with it. This was my life the last few days.
I got the hole roughed in on the right side. I went really slow because I kept working on making it fit a little better. The cover needs some modification but here is how it will look.
This is my high tech way of aligning the segments. This fits pretty well so the left side I will just copy and it should be faster.
I think my hanger idea is going to work out ok. I thought I could just use a simple off-shelf part but I had to cut them all apart and weld the bits back togher at the right angles. I wasted too much time messing with it trying to use it as-is. Once I cut it apart it only took an hour to get it all aligned and tacked back up. The mufflers will get V-band couplings when the angles are all worked out.
Also, this wasted too much of my time this weekend. Seems like I was just stuck doing one sort of plumbing or another !
Next week finish the hangers, cut the left side hole and hopefully tack the whole exhaust together and have some feeling of getting this done!
