Nice job on the exhaust. I don't want to be the bad news guy but those hangers won't work that way.

You have the absolute right idea by keeping all the rods parallel so they can slide back forth as the exhaust grows, but those grommets will not stay in place. I know they "snap" together but they are actually designed to work with a through bolt that holds them together.

If you swap out the grommets and the brackets for a different style hanger, like the ones pypes sells or the universal parts store ones you will be fine.

You are absolutely correct but I have a trick up my sleeve for that:D
That was something else that I thought about but if I run bracket on exhaust and another on body w 3/8" bolt to hold grommet together. It will not give it room to grow. I'm trying to guide the expansion by way of hangers so it will not compromise the close tolorances to body at certain places.. I have the whole system tucked in there pretty tight. For now it's just theory I'll see how it behaves once I put some heat to it..
Good eye

Thanks fellas , been having more time to work on it lately

If you got it figured out, you got it figured out.

Some (useless) food for thought, at 400* a straight 10' piece of stainless tubing, 3" in diameter with .065 wall will "grow" approximately .300" This is what I was told by a machinist/customer with too much time on his hands who took home a 12" piece of tubing and reported back with his findings.......I'm sure you could get there with math, as well.

Not figure out yet, just theory.
Good info . I wonder what's normal operating temperature for exhaust?

Don't know temps but would like to know. Have mine tucked up really tight and floorboards got extremely hot, hot enough to melt fatmat under feet and rear seat. Now rapping exhaust.

Nice work!

Lenie Boommat makes a product for that. I've seen paper products get stuck and burn against exhaust, so count on more than 400 degrees I'd think?

Then again, coulda been my leaky engine oil...:D

Thanks phil

I'm going to shoot it with lizard skin , and maybe jet coat it / aluminum shields.
Ron what type of product is lenie offering?
