So that open end is behind my sliders. Still possible that it got gummed up but less likely. Perhaps getting some around the silencer affected the exhaust performance...???
Just looking at the scale and orientation it seems as though the silencer would have to be in the back corner, near the driver's side. I'm also thinking the orientation of it is flipped, maybe for a RHD vehicle, if the filter is near the rear/boot and the circled area terminates near the compressor, it seems like it's gotta be flipped.
