2 flowmaster 70's 3" IN (O) / 3" OUT (O) with an X pipe
or
1 flowmaster 50 3" IN (D) / 2.50" OUT (D)

im fairly hesitant to get dual offset 50's because i dont want a crap load of sound on the inside, just enough to get some attention on the outside

How about flowmaster 70 3" (S) in / 2.5" (D) out ? Sounds good outside, but not too loud inside. Click on the link in my sig to hear it.
