A car-clueless friend had his 2009 Outback fail its state safety/emissions test due to a “cracked midpipe gasket” according to the dealer, who wanted $1200 to fix it. A second dealer backed this up.

I looked at the car and the exhaust is not loud nor does it sound like it has a hole/leak. I even put it on ramps and crawled underneath and saw nothing in the exhaust that looked out of place, broken or leaking.

Is there something else on the boxer engine they could be referring to? He might have the part name slightly wrong as he knows zero about how cars work.
