CAT Bypass Pipe
 

Hey Wayne, or anybody else,

I bought the bypass pipe a while back and finally got to installing it today. I take it the threaded port is for an O2 sensor which I never had. What size bolt or plug will fit here??

Second question, What should the CO or mixture be set to without the CAT?

I think that you will find a O2 fitting plug in the exhaust portion of the Pelican catalogue. As for mixture set to 3.5% CO for best performance, 1.5% for best economy.
