I've had my Passport 8500 and 8500x50 for roughly 4yrs now. I recently installed a new exhaust on my car that makes it extremely loud when I go full throttle. It's also throwing a false Laser beep half the times when I do that. Does anyone know why? It never did this before the exhaust. Does the loudness of the exhaust have any connection to throwing off the radar detector's functioning? If so, why?
