Wrapped my headers tonight after trying the blu-buster. Blubuster did not work but then my headers were near black nearly all the way down..
I used DEI black 2". I wrapped the headers up to the chrome shields just past the lower bend. I tucked the wrap under the front edge of the lower chrome shields. Not the easist stuff to work with. I dunked it in hot water then started to wrap. I cut 18' for each pipe and that was about right. my overlap was about 3/8 to 1/2. I started at the head flange and worked my way down. I wrapped them outward aka top middle out then down around and inward, if that makes sense. The stainless tie wraps were difficult to get real tight. If I were to do this again I would use your basic screw style clamps. I pulled the wrap tight and squeegeed the water by hand as I went. Do this where you can get the floor dirty because the color does wash out. A tad messy plus it's all fibreglass residue. I'll let em dry and then I will use the DEI silicone paint and spray with a couple of good coats.
If I were to do this again I think I would cut all the shields off from the block to the bend and grind the pipes smooth...
I can take a few pics if anyone is interested with follow ups once their back on the TBA...
