I recently purchased a "X-duct" exhaust hose from Flight Systems (http://www.flightsystems.com/pdf/XDUCTflyr.pdf). I have an Onan 4000 which has a 1.25 OD exhaust pipe, the X-duct is designed for 1.5 OD. Anyone know where I can get an adapter.

btw: I went this way because the generator exhausts under a slide out and someone decided to cut a hole in the slide gasket to run a cable or something. So 24" above the exhaust pipe is a quater size hole where you can see into the coach. I have patched the gasket, but would still like to get it away from the coach a bit more. Gen-Turi would be awkward since the slide is in the way.

Thanks in advance for any help/ideas.

Any muffler shop will have what you need.

I called around the muffler shops in Louisville and they do not carry pipe small enough and didn't have much for recommendations.

Use a 1.5 pipe with a 1/8th wall thickness as a bushing, this makes up the 1/4 difference.

Call Bluegrass Muffler on Shelbyville Road. They can make anything.

Visit a hardware store that has a well stocked electrical department, emt conduit is close and compression fittings are close to gas tight .

They will have radius formed and straight.

Buy fittings and test fit before long parts.

Measure diameter and maybe cut the last inch and use for pattern

I called Bluegrass first, everyone seems to consider them the best in town.

Thanks

japple....buy 1.025 pipe and have a muffler shop with a tubing bender, expand the end of the pipe to 1.5" They do it all the time on muffler repairs/installs.

"topdownman" was right, Bluegrass muffler can make anything. Once I shut the rig down for the season, I took all the parts in and he made me a custom adapter welded to the existing pipe. Looks and works great.
