I've never kept a car more than 2-3 years and never needed repairs. My current car has low mileage, looks like new but is 11 years old. I am learning fast about car repairs. I have only lived here for 8 months in central Phoenix and have needed minimal repairs. When my exhaust system started to rattle and made a deep throaty noise I feared the worst, a big bill. I could tell the muffler was sound but the issue was further in. I took the auto to a local well rated ( in Yelp) national franchised shop. The mechanic told me indeed it was not the muffler but all the brackets and piping upto the manifold needed replacement for $250. He already put the car down off the lift so I could not see it. I declined and went to Fry's. There I put down a towel, went under the side to look. An elderly man came up to see if I was having a problem. I explained what happened and he immediately told me to go to Gene at Mighty Muf'ler who was an honest local business. I went there, Gene immediately put the car on the lift, immediately diagnosed it was a rusted hangar clip, he fixed it, shaved away the connections on the connecting pipes and charged me $30. In this day and age to have an honest professional, I reccomend him highly. Even if it was more expensive, he took me underneath and showed me exactly the issue.
