Ceramic Coating vs Header Wrap

[LBZ]

I was reading up on ceramic coating in a snowmobile forum as I want to pull my heat shields off of my sled and came across an interesting link.
http://www.centuryperformance.com/exhaust-header-heat-wraps-do-not-use-spg-138.html
It is mostly gasser stuff but good info none the less. Some interesting info in there and along with some other articles I have read, ceramic coating seems to be a much better way to go as opposed to simply wrapping pipes. Downpipes I think would be the only thing I would wrap.

Either,ceramic coating or heat wrapping will actually result in more power..Looks trick too!
Ceramic looks way cool,wrapping doesnt look bad and is way cheaper.

You should do both.

 

[Otts]

You should do both.

Agreed.

Dale the place that did my pedistal is the same place that stu did his stuff for his sled

I have the number in the garage or ill ask Alamo since they are doing the turbo for me right now.

I wouldnt do the header wrap on the sled.....it will always be getting wet JMO

Does anyone wrap there up-pipes??

I wrapped mine.

I wrapped mine.

mine too

Cool.

Ya the argument for the wrapping thing pretty much summed up was that the wrap retains moisture and lots of guys have found that after a couple years their pipes had bad rust and almost rusted or did rust through in some cases!!

there is a theory over on CompD that outer coatings keep the heat retained in the metal longer, making it more prone to fatigue. one member suggested coating only the inside, so the heat would not be absorbed by the metal as long. he said his result form comparisons showed longer lasting welds/lower egts/better spool. however, i have not heard this theory anywhere else. discuss.

Just ordered a full set of Levi's turbo and header blankets. I will post results once I try them out. I hope to lower spool time and cut down under hood temps. -Curtis

Who is that?

I personally feel the metal thickness, quality & the welding process has more to do with fatigue & cracking then anything else. The only way to test his theory properly would be to make 2 identical pipes at the same time, same welder, coat one outside & one inside, & run them to failure... I would be nervous of the coating coming off inside the pipe & going through my turbo's. Anybody know if ceramic or high temp. powder coat will flake if it doesn't adhere properly?

Yes it can and will if subjected to enough heat. I have seen it flake off of pistons a couple of times. But I think that had more to do with difference in expansion rates between the two materials. It is very hard to properly prep the inner surface of any exaust system. This in my eyes makes the process a little questionable.-Curtis

I wouldnt run it on the inside of a up-pipe either....it would also be pretty tough to make sure it was spead out evenly or for that matter even make it to the center of the up-pipes

As far as the exhaust on the sleds I would get them done on the inside JMO

I haven't had any luck on the inside of the two stroke pipes. It is almost impossible to remove all the oil residue. But it works awesome on the outside of the expansion chambers.-Curtis

Ya i could see that

A place in Edmonton that did another guy I know's sled pipes. He said they are very reasonable.

The general consensus in sled land is to do the inside when the pipes are new but I think with a bunch of brake clean and maybe blow sand blasting sand through it should get them pretty clean. A caustic cleaning tank like the use for prepping for powder coating should clean them up fairly well also I would think.

Probably the same would apply to doing any exhaust piping on our trucks, but I could see why someone would want to avoid doing the inside of them in the event they flaked off.

Book marking this thread. I need to call him up and get blankets on order.
