My darn muffler fell off and now my car is loud as heck. Im wondering what variables led to my darn muffler to just fall off. One thing about the honda civic when there is no muffler on it, it is very loud and annoying. I want to have it fixed, but also want to know why my other one came off. Not only just came off, but fell off. So I no longer have a muffler. If it would have given me a little warning, this wouldnt of been an issue and I could of just grabbed my old one before it fell off.

Why did this happen?
