    89003 is rated 2.5 out of 5 by 2.
    Rated 4 out of 5 by from Works good Fit together well and was simple to install. Only negative was that several nuts were missing for the clamps
    Date published: 2018-03-26
    Rated 1 out of 5 by from Terrible fitment Head pipes were not bent correctly, had to go to a muffler shop to have re-bent. Instructions, or lack of, were impossible to read the diagram showing placement had bold font so small it blurred together. Flange plates didn't line up, used old ones. Lastly, pipes were all there,but numbers on them were wrong on two pipes. Was hoping for any easy install...Nope

    This is not designed for your truck, but with some modification you may be able to make it work.
