[Mr. B]

I use to "micro-manage" my exhaust sound too ..... I spent a small fortune several years back trying to get a specific sound out of an old Ferd I had .... I was somewhat successful ..... to answer your question to the best of my knowledge, a larger diameter pipe after the muffler will yeild a slightly louder sound, but not enough to justify the cost .... I've been led to believe that replacing the "Y' pipe will not yeild enough performance gains to justify the cost of it either .... the computer that controls our engines does not allow much in performance gains and untill that code gets hacked into by the aftermarket, enjoy your FloMaster.
