Craig, my son expects that Jayco, to protect itself, will reply "please have it done by an exhaust system specialist." If that is the case I'm going to check with our local MIdas branch.

All based on your recommendation of course. :)

Thanks

ps. Attached is photo of the car he built from the ground up. He has
even got an engine - and he start from a block of aluminum. He has had
it running but there is a lot of work still to be done including the
engine management system. It is 600CC, turbocharged and he expects over
220HP - which will move a 1000 lb car along fairly rapidly.

Hey, I used to crew a DSR years ago when they first hit the SCCA. We had
been running a Swift DB-1 Formula Ford and switched to the DSR Cheetah
chassis. I'm no longer actively working on the car, but Bill just
replaced it with a Stohr chassis which is the hot setup right now. It's
gone way high tech compared to when we started and the prices have
really changed....like everything else :-)

Take care,
Greg

This is the reply I received this morning from Jayco Warranty:

Good to know they'll stand behind it. Maybe I should put in some
emergency repair supplies before we head out for Williamsburg tomorrow.

Take care,
Greg

And attached photo is the temporary (?) fix that I sent off the Jayco a
few minutes ago.

Certainly looks strong enough and the other comments cover everything I
was thinking. The noise issue might be the only aggravation and the fact
it will allow the pipe to bounce up and down to the limits of the links.

Take care,
Greg

I'm going to see if I can get a forged eye bolt with a collar and that would remove the issue of fatigue and breaking - but even with the current eye bolt that is unlikely since the weight is not very high. I may put in a piece of pipe hanger to prevent up and down movement. The previous hanger was made to flex front to back as the top and bottom were connected by a flexible section. It was that flex that caused the fatigue and brake in the weld. That shouldn't happen with the chain.

For what it's supporting I would think the one that's there would hold
okay. If you have a marina around you could find a forged eye bolt there.

There's usually some form of vibration mount incorporated with exhaust
mounts to prevent the vibration from being transmitted directly to the
welds. Mine had the steel strap welded to the frame and then there is a
piece of material resembling a chunk of tire between that and the mount
around the pipe. Probably the same as what you had by the looks of the
broken strap still attached to your frame. One of my mounts has a slight
tear in the rubber isolator so that will be trouble down the road as it
continues to move and wear. I'm hoping by the time mine breaks you'll
have the best solution worked out :-)

Take care,
