Hey All,

Are the new XERD O2 sims plug and play or do they have to be wired like the Toyomoto sims? Also, do you need a sim if you are just going to install the race pipe? I'm thinking probably, but I wanted to hear from those of you who have them. And yes I did a search for my first ? and no results.

Thanks for the nomal reply. I looked at my exhuast this morning and realized I would not need a sim since the o2 sensor is in front of the cat that the race pipe eliminates, but it was too dark to see anything last night when I made the post. Thanks again
