    17428 is rated 5.0 out of 5 by 3.
    Rated 5 out of 5 by from Love it! Sounds Great! The only mod I had to do was to cut the pipe just slightly to keep it from being to close to the spare. Other than that it bolted up perfect and looks and sounds great! Couldn't be happier!!

    Rated 5 out of 5 by from Great item! I bought this a few weeks ago, it went on smoothly after running into issues tearing the stock exhaust out. I am very pleased with the sound and quality of the system, and the fitment! Thank you JEGS!
