How easy is it to make your own exhaust manifold?

Are the bends fairly cheap?

Im thinking about it as i dont wana use my cast manifold from the donor but i dont wanna spend hundreds on getting one made.

I was thinking just a simple 4-2-1.

Thanks

If I can do it, any other idiot can do it.

I suppose it depends what you want. This is easy, 4 straight bits with bends in, then 3 Y pieces:





This is not:

Hi, I have found this company among the best for price, and there delivery is pretty quick. HTH Ray
OJZ exhausts

the only trick is getting all your lengths correct

Im going to build my own but only 'cos i have no money and it would take months to afford to have one custom made.

Can i do it in stainless aswell? I only have a mig welder

Im planning on wrapping it so not too bothered how the welds look

I paid around £125 for stainless bends and straights to do mine, took a couple of days to complete.

You can mig stainless but the welds will rust unless you use stainless wire and argon gas.

The trick is in how you assemble the bits during the build, do not weld up leaving bits you cannot access. If you get all the tubes to butt squarely you can hold together with masking tape before tacking.
