Single in Dual out is fine. However sometimes flowmaster exhaust can be loud. I bought a universal Borla 3 inch in Dual 2 1/4 out exhaust, and I am very happy with it. At idle in the cab is souds like you don't have a aftermarket exhaust on. However, when you step on it, it screams at wide open throttle, and sounds like a aftermarket exhaust on a Camaro or Firebird.

 

As long as you run cats you won't be to loud,when you remove the cats on a Flowmaster system you get to much of a metallic sound.
