I unscrewed one bolt on my muffler the other bolt I couldn't unscrew because there was a square nut on top preventing me from unscrewing it. I took one screw out and opened it up a bit so it is loud. By doing that does that effect my car in any negative way? Will it kill the car? My transmission went does that have anything to do with me unscrewing the muffler a little bit?
