I went to these guys because my check engine light was on and I knew it had something to do with the exhaust. They replaced my O2 sensors for less then a lot of other places and they did it very fast. About six months later the light came back on so I called them. They had me bring my truck back and fixed it again for no extra cost because the part was still under warrenty, they couldn't figure out what was still triggering the check engine light, but they worked on it till they had it right.
