Well I did it. the flowmaster is in.
It sounds OK, still a little rap when you get on it, not as bad as the 'Hushpower'.
My Apologies to Chiltons...
Anyway here are the promised 3 easy steps
1. disconnect battery
2. chock the wheels
3. Replace exhaust system
OK maybe I should expand on item 3 a bit.
I ended up surgically altering the flowmaster to make it fit. Anna Nichole would be proud.
I cut it down length wise to 8" wide and welded the plates back on.
I chopped off a corner as it was hitting the diagonal frame rail
I also had to expand the frame rail at the front of the muffler to get the muffler in far enough. I used my heat wrench (thanks Dad!) and a 2lb hammer.
I made the Y pipe from 4 pieces of 2.5" x 18" sections from the auto store. Carquest provided 3 90 degree elbows and 14' of 3" tubing.
I don't know how you'd do this with out a bunch of tools.
I used both my MIG and my oxy/Act torch, and well just a hack saw and more than 1 beer. It also took me at least 3 weeks working admittedly sporadically.
The boss says it's good enough!
All that is left is a few hangers and tighten some clamps
Pictures you say?
We got pictures

Looks very good.
I am impressed as to you cutting the muffler and making it work.

Very nice job!
Did everyone notice the coach is on scissor jacks.

Thanks,
And yes those are 5000 lbs stabilizer jacks. They will hold the rear, I've tried, don't know if they'd lift it or not!
I put them under for a little extra safety as the suspension was all the way up.
