"Had my Flowmaster 40 Series Delta Flow installed at a local muffler shop and what a difference!! I used my stock exhaust pipe and reconnected the stock tailpipe as well and am not diappointed. It took just a bit to get used to the markedly increase exhaust note but it sounds great! Very deep tone with just a slight amount of interior resonance around 2000rpm." —Mark M from Ada, OK bought a Flowmaster 40 Series Delta Flow Mufflers for a 2009 Ford F-150.
