a friend redid his and put the E-cutouts(2) right after the headers and then come down with a y pipe to one high flow cat and muffler and then out the back all with 3" pipe, It sounds great open being right at the header and he said it help, he is supercharge, I think I'm going to do the same

alright alot of people are gonna bitch about this but here it goes
i run a VERY small Magnaflow muffler on my setup, full 3 inch with 2 4in tips side exit, basically little to no restriction, when i had the truck on the dyno recently i decided to test the theory that a cutout won't help a N/A truck
I picked up 9hp and 11ft/lbs with an unlocked converter with no change other than an open cutout and these were nearly back to back runs
I pickup 5hp and 13lb/ft with a locked converter and this was over the whole curve
Unlocked is the first and third
Locked is 2nd fourth

I can understand it helping on your truck, however my little stock 4.8 I doubt the gains would be worth the effort....

my truck didn't pick up anything really with the cutout open, only 2-3 hp on the dyno which might not even be because of the cutout. If i were you i wouldn't worry about it.
