Building an exhaust mani, how much material should i buy?
 

I have to build a new manifold being my next turbo is t6 flanged and just to large to even fit where my current manifold is

How many bends should i get? how much stright?

What im ordering looks like i can get it in either 90* for 45*

5 90* enough?

how much stright? the 90's dont come with any legs
