Took my car in to get a muffler installed, and thought that everything was going to be fine. About 4 months later, I went out to wash the car and touched the tip of the muffler to clean it. The muffler started to swing back and forth and was VERY loose. I took the car into another muffler shop, and they found that the connection from the midpipe to the exhaust was corroded and was starting to become loose. They informed me that the welds used by Chatsworth Muffler were wrong and should not be used. \r

I inspected the rest of the welds when the car was lifted, and I could see many holes and definite signs of corrosion. It was a very shoddy job! I was baffled that I paid someone to do such a poor job.
Cons: shoddy job, corrosion
