The only rear that I remember seeing for a sedan is like the European dual exhaust. I am planning also on a rear skid plate/ diffuser so this weekend when I get under the car to take measurements I plan on removing the lower bumper and seeing about maybe altering stock piece. I have plenty of fibreglass and resign left from the last sub box I made. But I would rather get a one piece fibreglass or plastic piece.
I haven't spent a whole lot of time looking at my car from behind so maybe someday the badge will get moved or removed entirely.
Eventually someone (aftermarket) will show the sedans some love
