Berk 63.5mm High Flow Cat will certainly pass visual inspection and doesn't throw a CEL (MIL) code on either of the two cars I've seen with them. Just put the heat shields back on.



Just takes a little creative welding for some tabs:



A rock knocked the head shields loose and I'm currently running without them. Measured the heat under the carpet on the right side of the passenger compartment over the cat and it doesn't exceed 100°F. The OEM cat must get a lot hotter.

Thanks for all the help guys. I went ahead and bought the berk hfc with the 63.5 mm diameter. Another question can i install a 70mm exhaust system onto this hfc or would i need to get a matching 70mm cat? Thanks for the help guys
