I did a 4" aluminum exhaust last year and used. 5 feet of straight, 2 90's and 2 45's on my eg. Hope that helps you out.

 

Step one: Get a tape measure

Step two: Use it.....

If you have the knowledge to build this yourself you should be able to estimate approx how much material you should need with a tape measure. Always order extra though as I learned. Also keep in mind any bends
