I went to JSK through a reference of a friend. I had a a factory OEM muffler I bought to replace the existing muffler that was on the car when I bought it. I also had 2 chrome tips that I wanted put on the muffler. JSK first raised the car with it running and checked for any exhaust leaks. After reviewing what needed to be done, they said the total price would be 70 dollars. After watching them work and their attention to detail, it was well worth the money. They repaired 3 mounts for the muffler, replaced a section of pipe and found one leak which they patched. Excellent work. I would highly recommend them to anyone.
