Go to summitracing.com. Enter your info and you should be able to find which one. But I have talked to them and most of thier high flow cats will work as long as they match up on the pipe you have going in and coming out. I can't remember off the top of my head where you get the dummy sensors. Google "dummy O2 sensors" is how I found them. If you do replace your cats, there are 4 sensors. In the front of both cats and one being both cats. Your factory pipe should have places already there for easy install. Just make sure you have them put in after welding is done as not to burn them up! I hope this helps. Good luck my friend.
