David,
Not a direct answer but my pipes were no cheaper at Jethot coating. I have since spoken with the guys in the Gippsland area at HPC and they are similiar.
Wish I went there first..
.
My pipes are an aluminium colour. Colour is/was spot on. My early gallery pictures have the shorter aluminium/aluminum pipes. Then I swapped to a longer muffler and used black heat paint. I even covered the Jethoat coating with the spray can product..
I do not know about white. You may find trouble with keeping the bends clean at the point the pipes exit from under the front fender/guard. This does get a lot of rubbish off the road and the front wheels throw up a bit also.
Regarding the way they apply, I have since found out that my mufflers were rolled in a bead and water bath and that was why the inner was stuffed. They were full of white ceramic beads.
I cannot confirm this process, so I am only saying the pipes and coating is of a poor quality due to the coating flaking off and the mufflers being ruinned.
Re the coating, they did go dark immediately at the exhaust flanges at the head. A little later it flaked off around any welds.
My pipes were brand new and polished and prepared. They were good enough for chrome.
As far as joints, they painted the lot and I rubbed it off the inside prior to fitting until they slipped together easily.
I do not know if the end product was dipped or applied similiar to the powder coating process.
Perhaps ring HPC direct.
