PO420 no more!
OK, I went ahead with the replacement cat for the 2008 Reno from Rock Auto made by -Eastern Catalytic-it was $182 shipped. This part installed Flawlessly with perfect fitment , came with all new exhaust gaskets, mounting studs & nuts. No modification was necessary and that can be odd for the aftermarket. Only really need a good basic 3/8 drive socket set to do the job. Oh,and enough extensions to reach a good 12inches for one of the top converter to exhaust manifold nuts that is kinda tucked between manifold runners. Installed over 600 miles ago and still No PO420 Engine Light so far so good.
