Is Walker 82505 Cat converter compatible wit VGM2.4VJG2EK

Hello, no idea. You'll have to check with someone that has a Walker catalog for cross reference. I will say that in California, all catalytic converters must be "CARB Certified" to pass smog testing. Most parts must be sourced from your local dealership. However, there are a precious few aftermarket catalytic converters that are indeed CARB certified. Definitely ensure it is stamped accordingly, or it will be a waste of time and money.
