Wrapping the X pipe with titanium exhaust wrap

Wrapping the new X-pipe with titanium exhaust wrap.

[connorelsner]

The wrap is acting as an insulator (similar to a Styrofoam cooler, except keeping heat in, not out). This way, the excess heat exits your exhaust tip with the combustion gas rather than being emitted as radiation (into your engine bay) via the bare pipe. Because the wrap is an insulator, it's specific heat (how much heat it takes to change a given temperature span), and heat conductivity (a copper pipe always feels colder than a pvc one) are much larger than that of the bare pipe. Therefore, after you turn the car off, the bare pipe will cool quicker (again via radiation), and give the appearance that it was colder the whole time. This is not true, and is simply a trickery of heat and mass transfer. Fyi, I'm a chemical engineer with a background in heat and mass transfer.

Thumbs up for you. I have back problems too. I know how it feels when working on cars.

Wraps are designed to increase temps in the header, or pipe, normally used to increase the affects of scavenging (headers). They also reduce under hood temps but keep in mind that higher temps in the pipe will soak through the wrap. I think while the wrap is able to dissipate heat, while driving and there is air flow, the outside temp will be lower than a non wrapped pipe but when the engine is shut down the "heat soak" will be higher than an unwrapped pipe and show a higher temp.

Another great video Dan... you should do a dyno run video. On another note if the wrap doesn't get the under hood temp down to your liking you could always remove whole exhaust including headers, get them ceramic coated then wrap them again. The ceramic coatings alone can drop temps by 40%

I wrapped the exhaust pipes on my off road 4x4 Jeep Wrangler and it lowered the surface temps by about 100 degrees.
The wrap seemed to harden a bit once it was burned in. I would cook them good, then check your temp. If you're still getting weird readings, check your temp-gizmo's operation and calibration.

Look into ceramic coating, "jet hot" is the company that did my headers.
Coated inside and out.
It also helps the headers last much longer.

Yeah, I think as others have mentioned, the disparity might have been due to the wrapped portions retaining the heat, and therefore having a higher surface temp. Measuring ambients with and without might be a better benchmark. Although now that you have it wrapped, undoing that to get a "without" ambient reading would suck. :/

Happy to see you using fender covers!

The emissivity of the two surfaces you're inspecting with your handheld IR thermometer is likely very different and leading to some measurement error.

It sounds awesome! Have you thought about the challenge rear grill? (that carbon grill like the scud one)

[michaeljohnmarx]

Is the wrap not perhaps insulating the heat instead of dissipating it? What is the wrap supposed to achieve? apologies for the stupid question.

[The_Drive_Inside]

I have never seen anyone check external temp like that and I'm fucking blown away!!!... kinda thought that was the entire selling point of this stuff wtf man!! I wonder what's going on... so weird!!!

[PatrickGSR]

Dang, too bad you couldn't have done that with the X-pipe off the car! Wrapping stuff in tight spaces is always a pain in the ass!!

[scottsmith]

It's easier before you bolt it on

[nettracher]

My exhaust rotted and cracked after i wrapped it with the same stuff you're using.... I would not recommend it

[RobertKohut]

Never be "a-frayed" when you wrap your pipe....LOL Be brave!

Why in the world would anybody need a remote control cutout....
Install a switch FCS.
