I need some help if anyone knows what I need to do. I just recently change the engine in my 2006 Range Rover HSE 4.4. Everything went fine, until I went to connect my exhaust back up and it seems like the exhaust pipes shrunk about six inches. When I try to push them up to the engine they hit the bottom of the car. I have the motor mounts connected and the engine seems to be sitting all the way down. Not sure what I need to do, any suggestions?
