I'm sure it's been discussed but couldn't find it.
I don't see many photos or discussions around exhaust heat wrap on FJ's headers so I'm guessing it's not encouraged... but I'd like to know everyone's thoughts about it. I've seen it used on 1250 legend cars so clearly some people use it.
No heat wrap on these beauties...

You know that all the '86-95 FJ single wall header tubes are stainless steel?
Pat,
Are the double wall pipes stainless? I just ordered a set that I am hoping to make nice and shiny.

86FJNJ,
I have heard of riders getting the exhaust pipes ceramic-coated, either clear for polished pipes or in colors for personal preferences. Holds in the heat, protects the pipes from oxidation, maybe other benefits. I have not tried it, but you might want to check out the results with those who tried the ceramic coating approach.
Thanks for the input. I plan to use some exhaust wrap where my slip ons meet my collector because I have a slight leak even after changing the gasket so going to put some heat wrap around it. Since I'll have extra heat wrap just wondering if it was worth wrapping the headers. I def don't want to spend money on ceramic coating these pipes just figured if the engine ran any better or cooler from it I might try it.
I did the Swain Tech "White Lightning" coating on my collector box, it seemed to help.
Dan, the 1984/85 FJ's had a double wall header tube with a black chrome finish. They are not stainless.
Be very careful with the black chrome on those tubes, the chrome coat is thin, when scrubbing off the cooked on bugs it's very easy to rub through the coating. Don't ask how I know this....
Around 12 years ago, while on a FJ West Coast rally, 800 miles from home, my '84 the oem double wall header tube suffered a cracked inner tube. The bike had about 120k miles on it back then....the clanging noise from that broken inner tube was crazy loud....I thought I lost a rod....still that beautiful bike got me home.
After that I converted over to the '86-95 FJ single wall stainless tubes....and yes, I too like shiny things LOL.
Cheers
Pat
I had the stock down tubes on the 89 black powder coated. As well as the header of the supertrapp chrome ceramic coated. Both to maybe help the chin spoilers to last a little longer. And because it's supposed to help scavenging. I don't know if it really does. But I figured with both possibilities. It might be worth it.

86FJNJ,
You can hide the bolt behind the pipe. The car guys call this gadget an exhaust clamp:

Red, even with my clamps I still have a leak.

86FJNJ,
Real duct tape (not the cloth crap) is a soft, heavyweight aluminum foil, with an aggressive adhesive. Cut strips of this tape as wide as the clamp. Wrap the smaller pipe to make it the same diameter as the other side of the connection. Then wrap the connection with several layers (at least) of the aluminum duct tape. Install the clamp. The clamp will crush the aluminum down into any crevices, and should make a good seal. Tighten the clamp again, after some riding.
HVAC supply houses should have real aluminum duct tape, but call first. I use that stuff for lots of jobs.
Do you have the exhaust gaskets in there?
That photo looks like the muffler tube is cinched down like there is no gasket. Also it looks to be leaking from the split also which will not seal without the gasket.
We have the gaskets in stock. https://www.rpmracingca.com/proddetail.asp?prod=Exhaust%3A3XW-14714-00-00

Yes it have a gasket, ordered new from you ;-)
I took it apart and set the gasket in the muffler first then put it on the collector which is the opposite of what u did last time so I think I got a better seal now but I'll keep my eye kn it
The gasket needs to go into the muffler deep enough to block the split to allow the material to clamp down.
