i"m planning on building my own headers for budget reasons!! and most of all to be able to say "yea i built it all myself" so is there a website that sells the neccasery tubing,elbows, and flanges for the heads and any advice for what thickness walls of pipe? and this will probably be a log style header for the extra clearance to fit the down pipe. also is there any major modifications to any wiring or hoses i need to know about other that heat wraping everything? this is going on a 2007.5 chevy 2500hd.

 

Call up your local metal dealer

 

Find a local industrial piping supply house in your area.

 

ok. but is there any advice on what thickness the wall needs to be so it dont overheat? i ran up on a similar thread after looking for almost 2 hrs and they said at least .120 which i believe shedual 40 is that or more but i was thinking .200 sounds better? on second thought .125 is 1/8 inch so what do you think of that? i live in a 3,000 population town there is no local pipe folks that was why i asked of a website. thanks for the replys i try to find my answer in old threads but i'm working 7-12's and dont have alot of time and im trying to get my stuff together and ordered because i won't have more than 15 days to do my build before my next job or i'll have to wait another 6 weeks and i'm geting ancy for that whistle and extra 100hp at the wheels at 5.8lbs i hope.

 

I know Tube Bending & Fabrication - Columbia River Mandrel Bending sells it at a decent price, not sure if you want it already bent or what not, they also sell flanges, v-bands, and what-nots. Im not sure about the head flange's hope this helps some.

 

Yea it did help I saved it in my favorites lol but their flanges are for the old circle ports I have the L92 heads? ( I think that what there called) and they're rectangular ports. So does anyone know were I can get the flanges for the n
ew heads?

 

You do not have rectangular exhaust ports.
