Holes in exhaust

Are these he holes where a small heat shield was welded at one time? if so then I would take it somewhere and have them weld up the holes. the factory pipe is far better than any aftermarket garbage you can buy. My V-10 Excursion did the same thing. I welded up the small holes and never had a problem.

Shop that does exhaust work should know enough to keep ground connection close to welding area. You should have no problems.

Found a shop that bends tubing and using welding to connect pipes. My concern now is damage to electronics due to welding grounds. Big truck shops said that is main reason for refusing to work on rv. I can disconnect battery connections but don’t know how to disconnect Allison wiring and other components. Worth the risk?

That should do the job. Brush or clean with sand paper and follow instruction on package.

Depending on the motor home
My Intruder it was possible to work wheels down
You can also lay 1x12's down Take like a 4' and a 2' lay the 2' atop the 4' (glue it there) and drive six (Assuming duals on rear) up on the top plank That fives 'em an added 3 inches and very very safe.

I got my exhaust parts for my 2007 fleeywood bounder w22 from ultrarvproducts.com

I have always used a hi temp epoxy resin. I think this on is an acrylic resin. As long as it good for 350F or so it will work. Some of these wraps have aluminum mess or foil for added strength.

If your local muffler shop won't work on it without it being lifted just remove the pipe and take it to them. Have them fabricate a new pipe and install it yourself. Or maybe a 100 dollar bill will persuade them to do something they normally don't do.
