the stock accordian style coupler has a little hole on the driver side of the coupler where some type of sensor was before. the silicone new one does not have a hole at all. should i put a hole in the silicone coupler, leave it alone, or what. also, i have the donaldson kit, tb bypass kit, mat sensor relocation, anyone else have positives or negatives about this set up thanks a lot.
