Have a huge chunk missing from the cat pipe, between the rear O2 sensor, and the cat. Planning on pulling the pipe, then pulling the two O2 sensors, then putting in a new cat pipe.
Appears that there's two versions, 49-state (no CA), and 50-state (CA). So for Walker, the 49-state is the 52284, and the 50-state is the 82673.
Yet... what's the difference between the two? Is there a significant difference, such as 1 vs. 2 O2 sensors, or is it something as mundane as you're paying for the CARB sticker?
Will check under-hood for a CA-sticker (we're in MI), yet hoping someone knows what the practical difference is, between the two. Thanks!
