I was just driving home from work, no issues that I can recall...stopped at a red light. As soon as the light changed and I started to go, I heard a slight bang on my back passenger side, I thought for a minute someone rear ended me but there was no impact and no one close enough behind to have tapped me. I continued driving and the engine sounded louder and the pick up was was struggling a bit. I pulled into a parking lot and went to the back, and it seems like my exhaust pipe was loose. I gently touched it and it swayed side to side, so it seems like the muffler is loose. Got home and did some googling and of course, there are a myriad of issues that could be the case. I’m going to see if I can bring it in tomorrow morning to my mechanic, but would just like some guesses at what I could be looking at here. The car is a 2011 Honda Civic, with 42k-ish miles. I’ve kept up with oil changes, fluids, and they’ve done some maintenance over the years like brake pads, and tire pressure gauge. I’m hoping this isn’t going to be a big ordeal!
