The dealer scanned my Subaru for ten minutes when the check-engine and EyeSight lights came on together, then quoted $2,100 for a catalytic converter. A coworker sent me here for a second look. Saskia smoke-tested the exhaust and showed me a photo of grey soot leaking from a split $38 gasket just ahead of the downstream oxygen sensor. The whole job, diagnosis included, came to $240, and six months on there has not been a single warning light.
