Photos of 1994 generator exhaust?

Post by DavidP »

I kinda feel that the exhaust on my generator is going to be more then one kit. I can't find any information or a parts list for the pipes. From where the hanger is near the front of the rear tire and the pipe kits available I would guess I might need at least 3 kits. If anyone has some pics and Onen/Airstream part numbers would be appreciated. Thanks

I took some pictures for you but I'm not sure they are all that helpful. Mine is also a 94. Looking up toward the generator box here is an overviewImage

And the tailpipe from belowImage
And from the van exterior Image
Sorry, I could not find part numbers.

Thanks Keystone. I see now that it is actually one complete piece of pipe, not multiple components.

Just a follow up on my gen pipes. I purchased the correct thin wall .052 tube with a OD of 1.250 from a company called Stock Car Steel in North Carolina. Also purchased a Onan resonator 155-2449. Purchased a cheep ($50) used hand pump hydraulic pipe bender sold by Harbor Freight and went to playing. The top rollers will dent the tube so I made 2 sleeves to put on the pipe so it wouldn't dent. The first bend out of the generator was about 13 inch down and not quite 90*. At this point I could line up the hanger with the pipe to guesstimate my next bend that was somewhere around 70-80*. After I got the bends and alignment spot on as pictured in Keystones pics I cut out a section of pipe before the hanger and mig welded in the resonator. Cut a slit in the pipe at the generator like a real pipe. New clamp and hanger. The thing is super quiet. The noise from the generator is actually louder then the exhaust.

Sounds like a success. Thanks for following up. How about some photos of your handiwork?

Looks the same on my 93 just replaced it all and added a resonater it really helped quiet it down. DavidP has given you good advice it does make a big difference i took mine to the local muffler shop $65 i supplied the resonater hanger and chrome tip. Amozon has it all.
