I have a 2011 Regal CXL 2.4 with 45,000 miles. A very cared for car, serviced every 2500 miles. The flex pipe is leaking, which I find odd with such low mileage. The whole exhaust system looks very aged. Has anyone had a similar issue? I am going to the dealer and hoping it will be under warrantee since it is part of one of the two catalytic converters, I guess they call the center pipe a pre-converter.
