My check engine light came on and I took it to an auto shop to get it diagnosed and fixed. They read the code and quoted me an outrageous amount to fix it! Needless to say, I was not happy. So I search the internet and found Reliable Muffler. Don quoted me several hundred dollars less to fix my catalytic converter and was sensitive to my timeline. He quickly noticed that the exhaust leak may be the soul issue and instead of just replacing the catalytic converter like I had asked, he called me up and recommended I get the exhaust leak fixed first because there was a good chance that the catalytic converter did not need to be replaced. I am very thankful and impressed with Don and his integrity. I will take my car into him for all of my muffler and exhaust needs from now on because I know that he will treat me fairly and honestly.
