Reddit mentions: The best automotive exhaust heat wrap

It’s not hard, just take your time with it and make it looks pretty. I used 1” wrap, I like the look of a tighter wrap though. And it claims to “increase performance” because your keeping more heat away from the engine, not sure if I buy that or not, I did it for cosmetic purposes tbh lol. I think it looks awesome, here’s a link for the stuff I used :)

Hmmm...I really dont' want to use the flex joint because I can't weld and I don't think it'll be flexible enough for what I have in mind.

My application is as follows: I have a backup generator on my property and want to enclose it in a shed. I still need to vent the exhaust gasses though, so for that I have a separate pipe with its own support structure to do so.

However I need a way to connect the generator's exhaust with that extension exhaust...and due to massive vibrations I'm looking for a flexible connection.

I hope that made sense.

So in all honesty, I'm still looking for a fabric-like alternative...just something I can wrap around the connections of the two pipes...and flexible enough so that the vibrations don't damage the shed/pipe/generator itself. The seal doesn't have to be a 100%, just so taht most of the gas does get vented.

What are your thoughts about something like this or perhaps even this

looks great, maybe some DEI heat tape in either silver or gold for your air box? It will reflect the heat from your engine bay from heat soaking your air filter as fast. I use it for my supercharged camaro.

I use the silver just because of color preference, I hear the gold works a little better.

Purchased 50 feet of 2 inch wide heat insulation from amazon. Installed it pretty quick and easy. Be careful though, it's like fiberglass and gets itchy.

Maybe a bit of double meaning :)

There are others out there but this is what I have used for some time. The slip-ons I did on my FJR have been on for about 40K miles and are still good as of this last week when I pulled them apart to check.

It's cool that DEI has a kit specific for the 4.0L engines but to be honest you can do the same thing for a little less than their cost.

Does your XJ already have the heat shield installed? If not you can get it here. CBXCB060 SHIELD-EXHAUST MANIFOLD

IMO hood vents are the last thing you should be doing to address heat issues. It's a band-aid instead of finding/fixing whatever the problem is that's causing the heat issues (whether it's heat soak, overheating, etc).

Sorry to double reply, but I thought I'd let you know, after looking around I found out this sleeving is apparently just insulation for high temperature pipes and stuff. If you want, you can just pick up this stuff, which supposedly is the right material, and is sold by the foot for about six bucks. You even have a choice of color, between red or blue. That may be better than getting my half of an old sleeve.

i use the factory beaver barf foregrip, and i stuffed the inside of it with i number of layers of this:

works beautifully.

You're saying you're missing the hose that runs to the airbox?

Photos would help

Also, good catch on the heat being an issue.

Mine had a crack from heat, and I noticed dirt/oil under the area it covers. Also had petcock problems, so in trying to seal up the bike completely (decel popping from slip/stock header as well) I patched it up with Permatex Ultra Black, then put some high heat reflective tape over the bottom of it, then used a bit more Permatex to cover up the silver tape for good measure/cosmetics.

The oil return tank (technical microfiche name) began to split at the seam from the heat it appears. It also had pitting/slight perforation from what had to be heat on the rounded part that is immediately above the exhaust.

Here's the tape I mention, and there are dozens of similar products out there.

Disclaimer, I've never tracked a ST but I have tracked a WRX and when I was battling high outside temperatures I did a couple of things. First was running distilled water with waterwetter instead of a 50/50 mixture for coolant. I found it did a better job at keeping temps a little lower (monitoring using an Accessport) and just did a coolant flush after every track day to put the Ethylene glycol stuff back in.

Second I upgraded everything I could related to cooling. Radiator, hoses, intercooler, heat wrap, turbo wrap, oil cooler, etc. Anything I found that claimed it could help lower temps I tried. I even drove with the heater on full blast for a session just to see what it did.

Third was just being aware of temps while I was on the track and adjusting my driving if things got too hot. While cooling down my car I would really focus on hitting all my points and not worrying about getting the most speed out of a corner.

Wrapped my 701 header with the Design Engineering Exhaust Wrap

Did it mainly for looks and to keep my boots from melting. Should help with heat, even more so after I get my Arrow Can...

The header on my DRZ is very close to the radiators, after wrapping I noticed a pretty big decrease in coolant temperature (I have a TrailTech TTR inline gauge). I have had no problems with the wrap, just soaked the wrap in warm water and tightly wrapped the pipe. I used 1 inch, this is what I ordered: http://www.amazon.com/HM-FC-Titanium-Exhaust-Fiberglass/dp/B015OVUCAC?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_detailpage_o02_s01

I used VHT flameproof flat black coating on pipes i cleaned with scotch brite and a similar looking, but more stiff wheel thingy for my drill. i wrapped them with this wrap and used these locking ties to keep it together

If you wanted quick, dirty, and easy, you could try wrapping the exhaust in something like this. Probably not the best long term option though.

I wouldn’t say it ALWAYS cracks pipes. Cheaply made pipes wrapped can crack or rust under the wrap when the pipes get wet, and aren’t dried immediately by running the bike. Both my bikes have wrapped pipes, and I haven’t ever had an issue with the pipes failing.

I use this wrap on my bikes: Design Engineering 010127 Titanium Exhaust Heat Wrap with LR Technology, 2" x 50' Roll https://www.amazon.com/dp/B002R4U72I/ref=cm_sw_r_cp_api_i_gs6hDb2DE47FH

The color doesn’t fade, like the black wrap I’ve tried in the past.

I have a soft sided cooler with a removable hard insert. It's not the best at keeping ice frozen even with the lid shut. Could some kind of tape like this help keep the summer heat out?

https://www.amazon.com/010408-Cool-Tape-Self-Adhesive-Heat-Reflective/dp/B000E283S0?tag=operasport-20

The plan would be wrap the hard insert with this.
