Customer Review: (see review/s)
  • This of course is a little work not bad thou I read some of the reviews where some stated you have to remove the transmission cross member. So what just remove a few bolts let one side drop down support the transmission with a jack. I soaked all my bolts with PB blaster a couple times during the week then when it came time to remove them no problem. The exhaust and catalytic converters came in two sections which was good and the clamp and gaskets were in the kit and O2 port holes had plugs in them which you will have to remove. However for $300. plus some change this saved me some money and so far no leaks and they work fine and my check engine light hasn t came back on so good deal.

  • 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.
