    Good Fit

    The unit is a perfect fit and sounds great. It has the Walker signature mellow rumble. Just make sure you don't forget to get the gaskets and bolts before starting.

        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.
