    Mufflers are excellent quality. Problem was they were a terrible fit. I was replacing a flowmaster setup so I assumed they would fit as the representative said. New ends and hangars had to be fabricated to be able to use them at all. No problem with quality but installation was a nightmare.

    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

    Sound Great but....

    It does sound good but it could be a little louder. But if it was, I would hear it a lot more in the cab so I am happy with it. Fit perfect. little bit of a drone sound but with 8 gears the RPMs are always low unless you are on it but when you are on it, it sound great and also when you start it.

    This thing sounds exactly how I wanted! Rumble at start up, screams on accelerate and the drone is minimal. Perfect part for anyone looking to beef up the stock sound. I couldnt get my stock muffler off after much trying. Took to a shop and he tore it off and installed this plus weld for $80. I reccommend finding a small time shop and asking what they would charge.
