I have test pipes that been sitting around for my g35x 2006 and wasn't to put them on. I can't find any answer to trust. Can I twist my sensors directly into my test pipes no spacers or non foulers and drive with the engine light on fr a few weeks or months? Im going to get non foulers at some point I'm just not in a rush if the light is just a light. Iread it's just an annoying light and other people say car will go into a limp mode or run lean or suck gas. Some people even say its safe to just put a bolt in the rear sensor holes and tie up the sensor out of the way which they come with bolts twisted in the holes from the store. I don't want the car to start running like crap or randomly stop running.
