Great price replacement system

Complete kit comes with everything you need to install. Hardest part of install was breaking loose old exhaust, it was rusted together. It smoked pretty bad the first 10-20 miles during break-in. A lot more quiet than I thought it would be. But I was dealing with the factory muffler with several holes in it and it was extremely loud. I purchased for the low price.

Great system, easy to install!

The only thing I had to modify is the tailpipe had to be bent straight from it's stock angle. It was hitting the right leaf spring in it's stock configuration. Other than that, easy installation, good sound, not much louder over stock, but good tones.

Hi blake, This Dynomax Exhaust Cat Back Exhaust System includes a nice sounding super turbo muffler that gives a low, distinctive exhaust note. It's a free flow muffler for performance and good sound. Great question, thanks for your inquiry.
