Cant really comment on the ease of install since i took to a muffler shop and had them do it. Love the upgrade. Sound is not "hot rod loud" but you can tell it's not stock. Love drivine the truck now

Now that I have the Flowmaster Force II installed, I have but a single regret - that I failed to get one years ago. It has a subtle rumble at idle which comes up a bit as you put your foot in, but then stays about the same as revs go up, which frankly amazes me. It never really goes above a pleasant deep resonance / rumble. I would estimate maybe 5% increase in power and will test mileage on full tank. Had I installed it sooner - would likely have paid for itself.
