Umm...no.
My 2 cents says don't get rid of the center res, just upgrade current rear mufflers to something nicer. I purchased my svt with a straight pipe instead of a center res and holy crap did I rasp. Not so much when it was hot, but every other time it did rasp... oh and it drones like crazy on the highway. Just make sure you always drive your car over 3k rpms... under 3k kills your ears.
