After being refused by my old mechanic("too much time involved to fix it"), i called the awesome guys at the muffler doctor here in kansas city. I described my vehicle problem and Marc and Jon were very helpful and very willing to help me. There were so wonderful and very detailed and informative. They brought my truck back to life and in a timely manner. These guys are the professionals. These are great guys, honest and fair. Id reccomend anyone to them over others. 5 stars and a huge thank you. Thank you guys, i was stressed out but now im bright as sunshine. These are the guys you want working on your car!
