5 Star is a business with integrity. When other shops tried to sell me a whole new exhaust system ($900+), 5 Star solved my noise problem for the cost of welding in a foot of pipe ($75). When I needed a new muffler it was about the same. Most recently, I didn't even bother getting other estimates and went straight to 5 Star. Not only did they solve my noise for cheap, they pulled the (OBDC) code for my check engine light without charge (which I guess some shops want a fee for.) In summary, these are honest mechanics with real expertise.
