Fender Exit Header Build Kits: Chevy Performance LSX-DR

This header build kit has everything you need to bring that Fender Exit LSX-DR custom header together. Designed to fit the Chevy Performance LSX-DR heads. Great for building that set of fender exit headers for any roadster, racing, or performance application.

See why Stainless Headers Mfg., Inc has the most complete fender exit header builder kit on the market for building your own custom headers.

Included are:

• (2) Flanges: (8) American made precision laser cut 3/8" thick header flanges to fit the Chevrolet Performance LSX-DR Cylinder Heads
• (20) Mandrel Bends: 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) Stainless Mandrel J Bends (6" and 12" staggered leg lengths)
• (8) 90 Degree Mandrel bends (6" leg lengths)
• (8) 45 Degree Mandrel bends (6" leg lengths)
• (2) 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.
• 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 (Collector tabs included)
• Slip on merge collectors with a transitional exit (Collector tabs included)
• (2) 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, these are precision laser cut for a perfect fit between your specific primary tubes.
• (5) Purge Caps: This simple, but effective method for back purging caps works great. Each kit includes 4 primary caps and one collector cap.
• (2) 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
• (1/4 lb) Tig Filler Rod: Includes 1/4 lbs. package of filler rod Be sure to check out our Facebook, Instagram, and YouTube channels for continuous updates on customer projects, as well as how-to videos and information about our extensive product lineup
