I have a 3" Fox (SS) Catback exhaust which I want to wrap in Inferno heat wrap before putting on as it runs very close to the transfer box.
Any downside to this?

The headers manifold down to the first joint is stock and won't be wrapped.

Appreciate all tips/info...
thanks

personally i wouldnt bother, the transfer can handle it...

but if you insist, there is no downside, just make sure you wrap it tight and use hose clamps every 30" or so

I wrapped my exhaust because it was making the floor unbearably hot.

It helps.

I like wraped exhust where needed. Makes sense to do, but I could not argue with zltan ither

Does exhaust wrap not trap moisture when and cause the pipes to rust after a period of time? I have no first hand knowledge of this, just some guy at the hotrod shop told me not to use it when I started to buy some. He said to make a heat shield out of aluminum to protect my drivetrain and tunnel cover from the exhaust heat.

Sure it can trap moisture, most of the time its driven off by the heat but if left wet it will, and building a heat shield out of thin aluminum is prefered. But some times its just eayser and more practical to wrap the exhust.

Wrapping is not the best idea IMHO.

Drastically shortens the life of the pipe. Even Stainless.

Thanks very much for the info. I had the exhaust in before and ended up with a severe Transmission overheat and expensive rebuild. At the time I didn't know what could have caused it but having taken the exhaust off and putting back the stock exhaust I believe it was the SS exhaust casing the overheat. I have since added an aux tranny cooler but would like to keep the heat down as much as possible. The summer temps of 48+ deg C doesn't need my help to overheat things up.

Will give it a go and see. I will be using Inferno wrap (claimed to withstand 2000 deg F) 2" wide and 1/16" thickness.

I wrap my exhaust all the way to the muffler and have a heat shield above the muffler. This is all an attempt to keep the floor and drivetrain a bit cooler. They do make a difference. I figure I'll end up modifying my exhaust before it ever gets a chance to rust.

My 48*C I would not worry about rust in those conditions, just how to keep every thing cool!

Yup. Rust is the least of my worries. The a/c on the 100 is very impressive and so too the engine cooling system. In mid summer drives (OAT close to 50 or above) I've never had overheating problems, and other car drivers sit in my car to cool off.

Don't wrap it. I did that and yes it did rust out it several places. It did that in one year. No the headers and exhaust were not crap just not a good idea to wrap and trap the moisture in like that. Mud makes it even worse to keep dry.

i had the headers on my first cruiser wrapped and keep it to a minimum and not on a daily driver. my headers lasted seven months after i wrapped them. wrap definitely helped rot them out. that said, i do have some wrap on my 68, but the headers on there are cheap (less than $100/pr) and it's not a daily driver so if the headers rot and i can't get new headers for a while, so what, i can park the rig and drive one of the other ones. i need the tape on there for spark plug wires and lack of clearance.

Well its wrapped and in. The headers are stock and not wrapped. The SS starts just forward of the muffler and this is where I wrapped from. Moisture is not much of an issue. If I don't wrap it sits in the garden shed. So if it rots off well ....in goes the old stock exhaust.

Most articles I read mentioned it smoking off for a few Kms, strangely enough this did not smoke at all. I didn't get Inferno wrap but another brand called BMG Turbo wrap.

Thanks for all the info.

not all of the moisture that can harm the exhaust is what you would think (humidity or rain). as your exhaust heats and cools, you get moisture inside the exhaust. rain/humitidy will burn mostly off, but the moisture inside the exhaust won't
