Russ and Tim were excellent to work with. I had a catalytic convertor issue with my car and no appointment. They were willing to work me in and did so. I was pleasantly surprised that it took only an hour or so to replace it. I had other shops quote me about a thousand dollars. I was in and out of Performance Muffler for $250.00. I highly, and I do mean highly, recommend this shop. My "service engine soon" light is off, and the car is back to driving like it was before. I will recommend this shop to all of my friends and family for their exhaust needs! Thanks Russ and Tim for going over and above your call of duty! Much appreciated!
