Swain Tech exhaust coating

I got the exhaust system back from Swain the other day. The ceramic they do is not cosmetic or for corrosion resistance (it's a stainless system so corrosion is not a worry). It is only sprayed on the outer surfaces. It is advertised as white in color and is fairly thick. It is supposed to reduce radiant heat by 50%. We'll see!

In actuality, the coating is not smooth like Jet Hot or HPC. It is more granular looking and is more of a platimum color than it is white.
Cost to coat the system was about $500 which included the mufflers. It was only gone about 2 weeks including shipping time to and from NY.
Nice folks to deal with.

Dave,

A 50% reduction in radiant heat is a pretty bold claim.

Please keep us posted on how it pans out. I hope that

the Swain system works as advertised! /ubbthreads/images/graemlins/cool.gif

Dave, am I right this coating precludes welding, so the system is clamped together?

The system was welded together before coating. Further welding would require removal of the coating.
The clamp ring you see on the collector is a V type clamp from Burns Stainless that I used to make the mufflers easily removable.
Each pipe is a slip fit into the collectors. 2 weld on tabs on each collector and mating pipe hold the pipes and collectors together. Removing the system from the engine would be impossible without first taking the collectors off.

A 50% reduction in radient heat would be most welcome. I hope it is that good.
The owner of Swain said that the white color makes a good base/primer for paint should you want them a different color. He said that VHT high temp paint or anything similar can be painted over the white with excellent results.
I plan to leave mine white colored. I would have left them just plain stainless with no coating if they wouldn't have put off so much heat.
We'll see in a few weeks how well they do.

I purchased the SS tubing and collectors from Burns also.

Both companies are excellent to deal with!

Did you take some temperature measurements before coating so you could make a comparison?
