What makes our header build kits the choice of top fabricators?

Included are:

• Flanges: 1 American made precision laser cut 3/8� thick header flange to fit the BMW M30 engines
• Port Size: 1.615"
• Flange Stubs: Included are (6) preformed flange stubs to help speed up the fabrication process. These stubs are formed to the exact flange port shape, and come in 1 1/2" or 1 5/8" primary tube size.
  
• Mandrel Bends: We supply (8) 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.
• 3 into 1 Collectors: From there we supply a pair of our super high flow 3 into 1 slip on merge collectors with 3 sets of collector tabs. We can also substitute the pair of 3-1 merge collectors, for one single 6 into 1 merge collector. 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 2 different collector options:
• Slip on merge collectors with a straight exit (Collector tabs included)
• Slip on merge collectors with a transitional exit (Collector tabs included)
• 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 � lbs. package of filler rod
