Wildman's TJ is getting a face lift

[JMT]

P.s. I think the loose thermal shield would be on the outside. It’s good to have a layer of air insulation.

 

[Wildman]

Here's what I've got so far. I tacked a 45⁰ piece to the flange. This is where going to a band clamp if I eliminated the flange it'd give me more room.

Added a piece of straight pipe to get me to the bottom on the transmission.

Getting that piece back into place wasn't a easy task.

Right now the cable just clears the exhaust pipe.

That 45⁰ bend is barely rubbing on the JJ. I might have to dimple it just a little.

 

[Wildman]

I might pull the header back off to take a look at cutting the flange off or down some & adding a V-band clamp instead. It would gain me a little more room between the header & the upper control arm.

I'm new to this whole heat wrap stuff too. I'm also wondering if I could use header wrap on the section that is going past the cable?

I just ordered two of the cat wraps.

Figure it's a can't hurt type thing.

I've found the DIY version of this I made to be highly effective.

I'll have to go back and look at your build thread. Do you know around what page it's on? I don't remember you doing this.

Thanks.

I think I want to try to flatten/dimple this area circled in Red. And then I'm not sure if the pipe is contacting upper link bracket or not. Area circled in Blue. If it is then I need to clearance there also.

Ideas or suggestions? Thoughts? Or should I think about trying to install the V-band onto the header instead?

What size pipe are yo using?

Obviously I'm not there and pictures only show so much, but could you heavy tack those first few pieces together and then flatten them somewhat into an oval shape in that area red and blue area where you need a little more clearance. If you oval the pie you shouldn't lose any inside area as opposed to dimpling it..
Just a thought..

2.5" That is the size of the flange.

I did flatten it a little bit but want to play with it some more. I ran into town to get some bolts and other parts and of course the hardware store closed early today. I'll check to see if I have some bolts in my bolt bins. I think I have most of it figured out now.

 

[Mike_H]

How much flex do your engine mounts have?

 

[Wildman]

Not a lot. They are a rubber bushing with a bolt running through them. I think that pipe will self clearance over time.

Edit: I'm more worried about what the heat will do to that JJ & the grease in it.

 

[Wildman]

Here's some close ups of the JJ & pipe. The pipe isn't touching the JJ but instead the jam nut. But how much will it transfer the heat? And I need to flex it a little and see what happens too.

And from the outside looking in.

I know you coated your last y-pipe and I don't remember the material but are you planning to do the same?

That transmission cable is worrisome but maybe enough heat shielding will do the job. I'm not a subject matter expert in that domain.

I'll express my own concern that the Johnny joint bushing is so close to the exhaust. I don't know their temperature tolerance.

I had them ceramic coated. I'm not sure if I'm going to have these coated or not. I've spent a ton of money on ceramic coating and now just have them laying around. with all the tight tolerances it might be a good idea for me to take the extra time to do it.

It'll be a learning experience for all of us. Other than costing me money and down time it's not a huge deal And I'm going to space it out as far as I can away from the exhaust.

I don't know either but again it'll be a learning experience for all of us. This again might be the reason to get it ceramic coated.

Does the ceramic coating give you any heat dissipation benefits?

Acknowledge and appreciate we'll all learn with you on the heat consideration for the transmission cable and Johnny joint. Hate for this to be another ' first timer' learning for you!

Ceramic coat when done inside & outside the product is suppose do help cut down on the heat felt through it. So yes it should help with all the items that are close to exhaust. IT's also supposed to help with scavenging of the exhaust pulse because it flows through the coated pipe easier?

I guess someone has to do it. I of course don't want to be "that" person but it appears I am.

This is what Performance Coatings says:

Performance Coatings offers high-heat ceramic coatings capable of withstanding exhaust gas temperatures of 1300° F in our Chromex finish and over 2000° F in our satin finishes. These coatings possess excellent thermal barrier characteristics, providing a dramatic reduction in radiated heat. This means reduced under-hood temperatures, accelerated exhaust gas velocity, and a longer life expectancy for the entire exhaust system, not to mention their chemical and corrosion resistance

Man, watching your exhaust work is giving me nasty flashbacks…



You’ll get it, Brother. But it’s never easy.
