    "the product that I ordered was delivered on time that was promised and all the items were included.the installation was not complicated due to the parts all lining up in place having the part come together where it did made the installation a breeze I was able to avoid removing any cross members etc." posted by: kreid on July 7, 2014

    "This rather complicated catalytic converter turned out to be relatively simple to replace especially since it came in two pieces so it was easier to install the new one than it was to remove the old one. The part(s) fit perfectly and everything works great. I removed all 4 O2 sensors and cleaned them before installing them in the new converter; and the whole system is working fine. No more engine codes! The price was better than any other place I looked; and the free shipping was a blessing." posted by: Don M on May 12, 2014 view all 46 reviews
