To run cutouts or not run cutouts, that is the question.

I think you need to go with what you like. There is a performance increase with cutouts, you're eliminating any choke down you get from the exhaust when you open the cutouts. I use mine for shows and parades. Kids love the loud pipes, and I can quiet it down when I just drive around with the family. I run iron manifolds into 2.5" stainless into 2 chamber flowmasters with turn outs in front of the rear tires. The cutouts are electric 2.5" and they're fun to mess with.
