Does this DP throw a code or not? Thanks!

That's the one I had. Threw a code and I used everything I could to try to trick the O2 sensor. Nothing worked so I ended up removing it. JB4 will clear the code, but it will keep coming back every so often, and since that's the case, you're better off going catless.
