Dean,
I am replacing my stock ERA 2" under car exhaust (all the way to my chrome tips) on my 351W; I am thinking of a 2 1/2" muffler with 2 1/2" pipes before the muffler and a 3" pipe after (for aesthetics) exiting in front of the rear tires.

I don't want to loose anything on the low end in favor the the high end; 2 1/2" muffler and pipe should be OK, right?
