Hedmans race plant is in either N.C. or S.C., they offer kits of bends of both sizes you need and they also offer either flange kits with welded stubs or plain precut flanges Summit also sells bend kits, check around for what you need. I ended up buying all the parts from Hedman through Summit to do two different cars, one with 2 inch kit and a 2 1/8 kit to make them step to a 3.5 inch collectors and the other is from 2 1/8 to 2 1/4 primarys into a 4 inch collector with welded 2 1/8 stubs I had Summit have Hedman drop ship all the the part to me direct Not cheap though, shop around first

Since we're talking about building headers, where can I get that star shaped filler piece that fills in the space between the primary pipes before the collector is put on? I don't know what that piece is called, so its hard to find it online.

that star piece was part of my Hooker collector, the tubes slid in til they bottomed out on the back of that merge point.

Check Stahl for header kits. I got my tubes and collectors from them and bought the W-9 flanges from SPD. They sell theirs in varying stages of completion and make a nice part IMO. As for the star , I liked Headers By Ed 's approach. He heats the tubes where they transition into the collector and pulls the inside of the tubes in with a needle nose vise grip , so where the four tubes come together get the appearance of a cross. He claimed this was worth 5 h.p. on the dyno as I recall.
Ed has a good audio tape on header building.

I priced all the parts for mine as coming to 700$ with having extra pipe left.200$flange,200$ for the collector,300 for tubing.
I priced out the stuff I used.Jegs 21/4 chassis header kit 555-31886 $130 They also come with 4"collectors Columbia River flanges and box of tubing and bends hf-ms38-bbm-200 3/8 flanges $30 each you can due 1/2 flanges for 10 more dollars I believe ubk-16-225-300-ms large box of bends and some straight $112 The box of bends and tubing was overkill.Just wanted to make sure to have enough.It did come in handy done the road for other projects. When I built a set we used 2" and was already started.You may even be able to do a set with out the extra bends.It sure made it easy with them though. You are looking around $300 to do a set in mild steel. Hope that helps!

I bought the Jegs 2 1/4" kit for a big block chevy. All I need now are the D-port Hemi flanges. Found them for a $100. I don't like the Jeg's collectors and will use a merge.

Depends on how much you want to spend and how nice you want it to look. I bought a header kit from Jegs and a few extra j bends from summit. You can also buy weld rings so the welds don't protude into the tube when you butt weld. When i decided I needed two tube around the frame I bought cheap slip on collectors from summit. I used steel tubes and mig welded them. Looks like crap on the outside, looks fine on the inside. https://board.moparts.org/ubbthreads/show...rue#Post7358657

It should all slip together. I always purge the tubes also, best way to get a good looking and strong weld on the tubes.

It's all up to the amount of room you have. That's the main factor My car being stock with T bars and stuff it's all a trade off. I just went big and unequal lengths. 2&1/4 with short and longs lol. It's hard get the fronts short with stock shocktowers. These were what put my car in the fives in the 1/8. I had hooker fenderwell supercomps and it would run hi O's. Only thing changed were headers and it went low .90's

they will be on a chassis car with strut frontend..only thing really there is the master cylinder and brake stuff is mounted in the floor...ill take some good shots of the front and the room I have .. the pass. side is open just the driver has the normal.....
Get a Hedman BB MoPar kit or SBC kit and flanges from anybody for the least expensive option. Step headers require a little more thought , but you have enough room to do anything you want header wise.

The "merge collector"? or just the piece with the 4 holes in it that is filler?
I beleive he is asking about the filler where the 4 tubes come together and form a point in the collector. http://www.coneeng.com/collector_components.html

For what its worth I just make the star.. stand 4 tubes on a piece of hard paper and trace them then cut the metal using the template... I tend to buy a slip on collector so I dont have to mess with the filler star To the OP... most times the package kits for a chevy end up being the cheapest... you will have plenty of bends and straight

Yeah.. I don't think it's worth that much of my time to go through all the steps of building it.
EBAY sells OBX 304 stainless collectors for $69 and I found a company that their price is even lower..$56!

Not sure if I'll use OBX but worth a look.
Have you used either collector or any of the products sold by these companies.That is a cheap!!It really makes me question quality!

Anybody ever use Schoenfeld collectors? If you have, how is the quality? I'm looking at their 1.75" x 3" mild steel slip-on collectors, and one place has them priced at only $36.00 each, which seems very inexpensive to me.
