Unfortunatly, its going to take a bit more than a muffler change to knock off .2 in the 1/8th mile. Compared to what you have now, best case scenario would probably be about .1 in the 1/4 mile.

To test the theory of reduced back pressure effecting performance; run uncapped to see if it effect your time.
