5 /5 Gav Details: I brought my 2020 Sierra to Action Auto Clinic in order to correct an exhaust concern. A semi custom true dual exhaust was already installed. I spoke with Art about adding an X pipe. I explained my concern and he thoroughly explained the first step in the process to "chasing" the issue. I contacted the shop to confirm availability, I dropped the truck on Friday night ( they assured me it would be kept in side ). The truck was ready on Saturday afternoon. The craftsmanship of the fabricated X pipe and the welds are top notch. Im very particular about my vehicles so its hard to find a shop to trust to do what you want the right way. The odd noise coming from the exhaust is gone, Im super happy with how it turned out. Its not easy working with someone elses work but Art did a fantastic job. I would not hesitate referring friends and family to Action Auto. I spent about 30 minutes talking cars with Steve too. A+ all the way
