Went to these guys it seemed so long ago but never had a chance to right a review. Had an issue with my cat being plugged up. They found the problem and help me out in solving the issue. We were unable to find any place that sold a catalytic converter for an 2000 gmc Sonoma. After lots of research I found one that was California legal. Had it shipped to them and once they got it, It was put on the same day. They do great work and now that I am in the area I am sure I will be contacting them again for something in the future.
