      This was an easy install once the old was removed, new cat fit perfectly and went thru emmisions with a passing grade first time, would recomend this unit to anyone needing a replacement. I consider myself just a backyard mechanic with limited tools and got her in with no problems not to mention the savings!

            Really was a direct fit on my 99 2wd blazer

            Use PB blaster to loosen the bolts before trying to remove.

                        the heat shield butts up against one of the hanger brackets on my blazer. Not a huge deal but not something that should happen is it is oe exact replacement.

                        fits great. Bolted on no problems. The first one the heat shield rattled like crazy got another and this one does it only some of the time. Still not good best option find another name brand. It cost $15 everytime i change for gaskets. not sure if I should try number 3.

                              No, Scott! This Walker Converter - Part No. 15827 does not come with the gaskets, you should purchase them separately. You will need the Walker Exhaust Flange Gaskets Part No. 31571 and 31589 for this converter.

                              Not necessarily a simple wrench can be used to remove an O2 sensor however there is a socket specifically for O2 sensors.
