My 20 year old Tahoe finally needed a muffler. Factory parts no longer available, so Justin ordered one that the catalog said was right. It was too loud. I thought I could learn to live with it, but after a four thousand mile trip, I realized I couldn't. I went back in, even though I hated to complain. He slid under the car with a tape measure and formulated a plan and ordered parts. A few days later, my car was quiet again! I had to fight him to take enough money, since he had to install two mufflers to make me happy. I'm very very pleased with Justin's work, and his welds are exemplary.
