Hi GBauer, thanks again for the pictures, I'll be printing them out.
I bought the backing plate from Langdon, it came with nice brass fittings. Unfortunately, I've got one pointed straight into a pipe (doh!). I was looking for the muffler shop to help fix that up. Or I just wait, the engine's coming out in 4 weeks anyways.
I'm a bit back to square one. The muffler shop I was going to use has a bad reputation, so I've found a new place to go that's unfortunately a lot further away. It's a header shop (Stan's Headers).
I don't know, but I may need to bring my exhaust system with me. What did you do for your exhaust? Bend your own? I found Waldron's exhaust, and that's it. So far nobody else sells for the L6. It's a 3-4 week lead time to buy, but they bend up their own pipes and will bend whatever size I want.
Thanks,
Mark
