I replaced the just original muffler with the 50 series It gave it a deeper throaty sound I was looking for. In fact it could have been a little louder. You will need to bring about 16" of 3.5 inch exhaust pipe to your local muffler shop for the install. For some reason they don't carry pipe that big

I narrowed down the list of mufflers to two (2) for my Ford 460. The first was a Gibson MWA. Nice muffler - but too loud. I settled for the Magnaflow. Once the exhaust was installed with a rear-exit tailpipe, the 3"in/3" out centered muffler had a low-rumble with no indication of resonance inside the cab, even while downshifting from a higher rpm range.
