The Magnaflow mufflers made a difference for my car in terms of sound and performance. Delivery was fast and quality is great.

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.
