so i have two sets of headers, a fenderwell set and a old set of cppas. I have a 68 b'cuda with a rb and victor heads have a motor plate manual steering and manual brakes and dual external oil line pickup. I dont want to hack the heck of of the car to loose truning radius with full on fendewell headers and the cppas dont fit for a darn, both are 2" primaries. is it possible to cut and weld and make my own set of semi fenderwell headers (ie proparts) with a 220v mig on flux wire? also where would i look for slip fit pipes or collectors?????

---

Many places have the tubing your looking for, try
Jegs or Summit or Google headers.... if your going
to make a set of headers DONT use that flux wire,
spend the money to get the 75/25 and a regulator,
it makes a MUCH nicer weld and looks much better in
the end... I tig all the headers I build but tack
tac them with the mig

I'm not the greatest welder, but silicon bronze filler material works really good for headers. It flows at a low temp, and is tough.

Tig most all ours with Stainless filler.

My Syncrowave 180 doesn't like stainless. Or maybe it's me. How long did it take you take good at stainless on sheet metal and header tubes?

Lincoln squarewave 200 amp.Do header and cage work with ss filler.Liquid cooled torch.So easy a caveman can do it

Yeah I've done a ton of silicon bronze, I had to
seal every muffler seam on all of the mufflers that
went into the exhaust certification for production
(ALOT of mufflers) just so we made sure we collected
all of the gases

Stainless is NOT the proper filler rod to use on a cage especially a moly cage or a mild steel one for that matter.Why would you use that? A caveman would even know that much!

You are absolutly correct SS filler exceeds the stength found in the CM and MS materials used and is not the recommended filler.With that been said,SS still can be used and is accepted since it makes for a stronger weld with more density.As long as your using a material that is compatiable and as strong as the material being welded or greater(SS)The only concern is it being done properly and the cost is higher.It's like saying CM must be welded with CM filler,if that be the case then every weld on a cage or chassis must be stress relieved.That you chose your knowledge and use your experience to dictate your methodology and application and I will not dispute your comments.I draw from my experience with techniques used in power plants,pressure vessels,heavy equipment repair,and structural building and bridge work.I also rely on advise from some of the best structural professional engineers.I will stand corrected by you but won't change my methods.

I use E70S for most tig welding I do on MS.

I TIG welded my Mild Steel Cage with SS filler rod.

Yes, it works, and yes, its safe. Got the tip off from a certified welder.

---

Yeah,just talked to our head welder at the construction co.He is also certified master welder in 5 states for structural and arial(crane booms an such)He says SS filler is acceptable and approved and recommends it for MS/CM and says 4130 CM with the high chrome content is similar in moleculer structure,density and strength.And that the only reasons not to use it would be it's not necessary and cost a little more.

Well we idiots that use SS have defended our position,and are waiting to here the facts as to why we are wrong,and especially on CM/MS cages since I don't think it makes a rats butt difference on the headers.By the way we build a lot of SS tube headers.Things are awful quiet in the cave.We read the statement but don't see the back-up support.Cause some one says so,doesn't give me cause to change my mind. No matter what it beats the days when we welded dragster chassis with oxy/acetl and hanger wire.
