Throw a sensor off? I dont think so.
Im not sure exactly what it does, but it will affect the performance of the car.
I have a 3100 SFI vehicle, I had a shop install a fart can in a classy style- done professionaly
Anyways, the car still gets good gas mileage, sounds mean, but its noticeably slower than before. Ive been told its because I no longer have any back pressure... Dunno, dont care... But I can say without a DOUBT there was a difference in performance for the worse
