All around I am happy with my purchase and I really can feel the power gain.

I had my resonator taken off due to a large dent and hole in it and couldn't stand the hum I would hear in the cab. I didn't realize how important the resonator was. I had this welded on and the cab is back to normal without the noise. I have also noticed a slight increase in fuel mileage / power. If someone says the resonator is not important and you won't notice with it taken off is wrong.

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
