I have an '87 Chevy 3/4 4x4 long bed. I just put a 4in suspension lift on it and now the front driveshaft is a quarter of an inch above the exhaust pipe where it crosses over to the drivers side. It is still factory single exhaust. Is the shaft going to move enough to hit my exhaust pipe? Or should I just stay on the street until I convert it to dual exhaust.
