The engine frame mounts are canted to form a "V" shape. The motor mount holes in the frame mounts are elongated. This allows you to loosen the engine mounts and rotate and reposition the engine slightly to gain a bit more clearance on that side.
Loosen the motor mount nuts on the frame mounts, place a board under the oil pan, and lift the engine a little. Shove the engine toward the passenger side and lower it back down. That will raise the engine toward the higher side of the frame mount on that side of the car and should lift the exhaust for more clearance.
