I'm sure 4" would have been fine for my current setup, but the outlet on the s400 that will be installed this summer (along with the s300 and a lot of other things) is 5", so I wanted to run it all the way back. As to how much better 5" is than 4", I've only had stock and the setup I have now. I gained 2 psi of boost going to whats in the pictures.
