welding header flanges
- Thread starter bill4u6

When I weld mine, I use a 3/8" header flange and insert the tubes half way into the header flange, then put a light tack on the inside. Next bolt the flange to a stock exhaust manifold and tack the tubes on the outside. This helps keep the flange flat. Now remove the stock manifold and weld around on the inside. Skipping around as you weld will also help prevent warpage.

exhaust tubing will work fine. Most of it is aluminized to help prevent rust. I needed some short pcs when I built mine and just went to the muffler shop. You can get the J bends lots of places so check around before you buy. I got most of mine from Advance Auto Parts.

if your going to build some headers, check on ebay for the "bulk" deals on bends, youll spend $60 on a box of 20 bends, which range from 45* to 180* and they all some leg on at least one end
i got a box of 2.25, but at the time the guy also had 2.5", 3" and i think 4"
they all seam to be rejects from a company that does mandrel bent exhausts

If you are near an ice cream or milk plant you can get stainless pipe that they pull out in upgrades if you know someone. A friend of mine worked at one when I lived in Green Bay We got quite a bit for cars we where working on. The problem is a regular bender has problems bending it. link to stainless pipe.
