The 2.5" radius just looked a tad small so I got this 4" radius (from Burn's Stainless, best quality so far) for the first bend and I think it looks much better; and in theory it should flow better. I got my two bends done for the second part of the header. It was 92 degrees in the shop and after letting loose with the big torch the temp climbed to 105. I was listening to my sweat drip off and sizzle on the pipe, don't want to do that again. Thankfully sand bending is over at this point. Need to fit them up and weld it all together. Eric also picked up a powder coater he was keen to try out so we re-powdered the top triple.
