Owner complaint summary
The mounting bracket welded to the front exhaust pipe (near the flex section) broke off due to weak factory welds. As a result tearing a hole in my exhaust pipe and potentially leading to exhaust fumes leaking into the cabin of the vehicle. In my opinion this defect should be addressed as a safety issue if not repaired.
