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!
