500 miles later cruising with the wife and car gets huge backflow into the exhaust, service light comes on and you know how it is.

Pull off and look under only to find a half dollar sized hole in the CNT HFC! On top of it, my O2 sensor is gone and only wires are dangling....ouch.

Forwarded 4 pics into support center today....
