You NEED a certain amount of back pressure to have use-able low-end torque for the "low" RPM range. If you remove a substantial amount of back pressure from your exhaust it will feel like you have to get the RPM range MUCH higher to accelerate at the same rate as you did before.
I agree a free-flowing exhaust will help you, but there is a limit where you can go too free-flowing also.

On a small V6 with a short stroke... I'd run a 2" pipe vs something larger. At lower rpms your simply not moving much air (exhaust velocity) and scavaging just isn't taking place. You will loose some low end TQ. But if your happy with the change.. who cares.
Reducing the back pressure will raise the TQ curve. So.. as long as you like the power and noise.. it's your truck. Do what you want to.
