Hello, new owner of a 2009 Grand Touring.

What options are there for a hi-flow replacement catalytic convertor other than OEM? I live in a state (NC) where we have mandatory annual inspections so deleting the cat isn't an option.

Sorry, found my answer. Think I'll go with the Magnaflow cat

the HJS metallic cat converters from Germany are the best, but not cheap. It also has to be installed by cutting out the OE cat and welding it in place or installed on a replacement aftermarket midpipe.
