Im most likely going to swap in a borla XR-1 with a 12-16" case.

If you are still running stock exhaust manifolds and cats, then I doubt there will be any loss in low end. I'm surprised you lost some low end just from a muffler swap on your old 5.3l. It could have just been the louder exhaust effect. Sometimes when the exhaust is louder, you think that you should be going faster. With full exhaust on my 5.3, I dont feel like I lost any low end. Could be wrong though.
