Hitch is bolt on so if you need to mess with exhaust you can easily remove the 4 bolts attaching the hitch to the car. Loaded trailer with about 200 lbs and took it for 200 mile test drive. Worked fantastic, couldnt even notice it. Made no noises at all and was cruising at 75 mph. I can finally load up car for trip and ride with top down (I prefer camping over paying $100 a night for hotels.) I am confident this thing could easily pull a lightweight aluminum boat as well. No noticeable difference in acceleration but i still ease off easier knowing the trailer is on there.
