Default Flowmaster 10 series and new pully

I think it depends on the engine setup and not solely on the exhaust alone if you want to add gains. Putting a new exhaust will surely make it sound great. you'll get more power gain if you have a combination of pulley, cold air intake, exhaust (stock or aftermarket) and tune.
