If I could give. Negative 5 stars I would. Had a check engine light on my 2004 Sienna with a code that said there was a problem in the exhaust back side of engine. These guys told me my entire system catalytic and all had to be replaced. Went so far as to say " if one part is gone gotta replace it all " wanted $2000. I waited and had a good mechanic look at it. It was a seal that needed to be replaced. Cost me $125. Please stay away they are bad. I really should if guess they were the shits when they were all sitting around with no cars to work on.
