Headers?

Headers 4-1 or 4-2-1?

Which would be a better choice?

I can have costum headers made here by a local welding shop, so thats why I need this info?
Is it a good idea? he's going to use exhaust pipe to make it.

Any input?

Thanx

now dont quote me on the but i dont think you can make headers of exhaust pipe cause its thin and headers are thicker and stronger....... but i could be wrong, also i have a friend who took his oem headers to a local engine shop and had them cut and welded diforent pipes that have been bored down from a 3000gt and he says he feels quite a difforence..

Doesnt sound like a good idea too me. What would they use for the bending?

no way with the exhaust pipe it would probably melt! you need to get the proper piping for a header and the right flat to make the flanges. i think you will need 1/8 inch thick pipe. i dont know the size of the pipe. that muffler shop is trying to take your money if he suggested to make it with exhaust pipe.

what is the thickness of the pipe above all else...

Many people make custom headers. 4-1 is for high end gain, 4-2-1 low-mid range gain.

so for a 1/4 mile 4-2-1 is better? or what do you guys recommend?
