Approach your dealer about covering this as it is not a legal system in any of my jurisdiction as it doesn't terminate outside the perimeter of the passenger compartment. Check the regulation in your area but I would find it amazing if any legislation would allow an exhaust to terminate almost 4' under the vehicle. I cover this in another thread...but yes you can terminate it out the side or back.
