I shopped around for a Catalytic Converter installation, and plenty of people wanted way too much money for popping 4 bolts. His price was almost half as much as my next closest estimate.
Based on my experience, I would strongly recommend this shop. The work is done by the owner, not some kid working for minimum wage.
