The good news is that the CAT fit without any modification. I had read other reviews before ordering, so I thought I had all I needed when I bought flange gaskets for it from the dealer. However. the original OEM CAT had bolts threaded into the flanges for it, so I had to beat feet to a lumber yard and get some bolts, lock washers and nuts. They aren't hear-treated, so hopefully they'll last as long as the converter. My HC at 25 mph went down significantly after the installation; however, the HC at 15 mph went down enough to pass but not as much as I expected. I can't detect much difference in power output with the new CAT, but at least the car is legal again in California.
