    • What makes our stainless mandrel bends truly a unique product? We start off with an American made 304 stainless raw material, that is then bent in the U.S. for a genuine 304 .065 stainless bend. Our material forms better, welds better and last because it is a genuine 304 stainless.
  • Purge Caps – This simple, but effective method for back purging caps works great. Each kit includes 4 primary caps and one collector cap.
  • O2 bungs – Each header builder kit includes 2 weld on O2 bungs. Precision machined in the U.S. from 304 stainless billet, these bungs weld beautifully, not like a cast bung
