(HP recommendations at the bottom of this page)
What makes our header build kits the choice of top fabricators?
  • Flanges** – Included are 2 American made precision laser cut 3/8” thick header flanges
  • Mandrel Bends - We supply (12) 180 degree J bends. Our J bends come with a 6” & a 12” leg. For most header builds, this extra leg length mean you won’t need to buy any straight tubing. 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.
  • 4 Into 1 Collectors - From there we supply a precision formed 4 into 1 collector or a set of our optional super high flow slip on merge collectors with 4 sets of collector tabs. Just like our stainless bends, we start off with an American made 304 stainless and fabricate the industries finest collectors.
We offer these header kits with 3 different collector options
Formed weld on collectors
(Collector stars included)

Slip on merge collectors
with a straight exit
Slip on Merge Collectors with Collector Tabs
Slip on merge collectors
with a transitional exit
Transitional Exit Slip on Merge Collectors with Collector Tabs

How To Build Your Own Headers

  • Collector stars – A simple part that really helps speed up the fab process. Used as a weld in block off between the 4 tubes before welding the collector on, there are precision laser cut for a perfect fit between your specific primary tubes.
  • 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
  • Tig Filler Rod -Includes ¼ lbs. package of filler rod
