I got my 3 inch exhaust installed :cool:
Man this thing is loud!! I installed my test pipe today (got even louder!). My ? is what have you guys done with your oxygen sensor that was in the cat? Right now I have my sensor tied around the exhaust. Will this effect performance? Any suggestions or am I OK? Thanks :)

It will probably throw a MIL light sooner or later. Have a bung welded in the test pipe and put it back in.

I had a resister put in my JWT ecu that eliminates the rear o2
