I have been trying to figure out my alternatives to jet coating. I have found heat wrap and DEI Hi-Temp silicone spray on the Buschur site. I am curious as to if coating my stock exhaust mani, eBay O2 housing, 3" downpipe, and 3" exhaust with the heat wrap and Hi-Temp spray would be as beneficial as jet coating?

How hot do these exhaust components get? Do I need the heat wrap at all or could I just spray these components with the silicone and have a similar effect? How many cans of spray would I need and how much heat wrap?

I have their HiPerCoat Extreme on my manifold and the standard coating on my heatshields, o2 housing, and DP and it looks and works great! The wrap causes accelerated corrosion due to friction and holding in moisture / morning dew, but if you had the stuff coated, you could wrap it as well and wouldn't have to worry about the corrosion.

 

Swain hands down. It's an actual thermal barrier not thin spray on paint.

 

jbrown: All of my piping besides the stock exhaust mani and hotside is stainless steel. Because of this I wouldn't worry too much about rusting. Even so, wouldn't the silicone spray lock out moisture?

I guess I am more interested in learning if the wraps and hi-temp silicone spray are effective. I appreciate your other suggestions, however. I may still look into those if the wraps aren't a good idea.

 

Can anyone from Buschur comment on this? I saw these items on their site, so hopefully they have tried them out on their own cars...

 

bump...

 

Just because it's stainless steel doen't mean it can't corrode. Rust and corrosion are two different things. You also have to worry about friction from vibration and the expansion / contraction of the pipes as they heat and cool.

Buschur would DEFINITELY know more about this than me, I just wanted to let you know it's not exactly a "yes or no" answer.

Heatwraps could also rott your header/exhaust -- just a quick link, google header wraps or heat wrap for more reading...

Actual coating is the way to go.

 

How are rust and corrosion two different things? Rust is corrosion.

 

no....

so if coca cola causes corrosion to the enamel on your teeth does that mean that your teeth rust?

 

sorry Joey....you are wrong this time.

"Rust is the substance formed when iron compounds corrode in the presence of oxygen and water. It is a mixture of iron oxides and hydroxides. Rusting is a common term for corrosion, and usually corrosion of steel."-- http://en.wikipedia.org/wiki/Rust

As an aircraft avionics/structural tech I deal with corrosion of metals be it aluminum, steel, titanium, and bronze. All metals corrode.

I think its www.performancecoatings.com

I can seriously touch my downpipe after a hard run. They coat it inside and out and were able to do my flex section. It's supposed to be good to 2000 degrees. Cost me $50.

Dont waste your money on wrap.

 

No dude, Joey is right. But you are both saying the same thing.
Rust is a form of corrosion, but all corrosion is not rust.
Rust is specific to ferrous metals, corrosion is not.

 

Ideally I would like to coat every piece of metal that holds exhaust but I can't afford that nor do I have the time to wait to ship it out and get it back. I thought wrapping the DP, O2 housing, and stock Exhaust Mani with heat wrap would be a good thing to do while I have them out of the car before I put it all back on Monday.

If I do not do the DP right now I would like to do the O2 housing and Exhaust Mani at a minimum. I want to do the O2 most definitely because it is aftermarket and I can't use the heat shield.
