Default Quietest 2.5" Mufflers for 69 GTO?

I have a SD Stump Puller cam with ported 62 heads and about 450hp in the 468 in my 69 GTO. Currently, I run AP Xlerator 2.5" mufflers with 14" case. I want to quiet the car a bit. These mufflers have an offset inlet and center outlet. I could go to the 18" case Xlerators. Would that be worth the swap or is there a quieter muffler with center outlet?
