I'm looking for a muffler for my 06 grand prix base. I just want a little more sound over stock. Does anyone have experience with borla pro xs, flowmaster 50, or thrust turbo? Thanks for the inputs.

havent seen any comparisons but I'd pick the Flowmaster 50 for a slight increase in sound and not having to deal with a drone.
