You can either run O2 extensions(the 90° ones work best), or run an electronic O2 simulator(hardwires in, and mimics a working O2 sensor). The extension is the easier of the two, and works most of the time, but sometimes you’ll need to play with the length of the extension(stacking extensions) to get it right. However….. If you’re going to pull the ypipe to do this, might as well try and find a good used ypipe to just swap in and forget all the headaches with knocking the cats out. My .02</blockquote>
