Exhaust Pipe Question

[osbornl1]

hey all i have a 2500 with the 6.0 and i have 2 flowmaster 40 series on it turned down right by the axle. sounds great but was thinking of running duals out the the rear at 45's

 

would 3'' pipe make it deeper with 4'' tips??

 

also i heard a 03-04 dullie with the 8.1 and a six speed the other day in jackson tn. and it sounded just like a harley motercycle. it was loud deep and poped when he let off the gas.

 

can i make mine sound similar??

 

also can anyone recommend shops in the dayton cincinnati ohio area??

 

Thanks for the input
