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

Included are:

• Flanges: 2 American made precision laser cut 3/8" thick header flanges to fit the Oldsmobile 3.5L V6 cylinder head
• Mandrel Bends: We supply (10) 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.
• 3 into 1 Collectors or 6-1 Collector: From there we supply one of our weld-on formed collectors, or offer an upgrade to a super high flow 4 into 1 slip on merge collectors with 2 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 5 different collector options:
• Weld-On 3-1 Formed Collector (2 1/2" Secondary Size only)
• 3-1 Slip on merge collectors with a straight exit (Collector tabs included)

• 6-1 Slip on merge collector with a straight exit (Collector tabs included)

• Purge Caps: This simple, but effective method for back purging caps works great. Each kit includes 6 primary caps and one collector cap.
