Does anyone know for sure whether a low-mount muffler intended for a 6th gen will definitely fit a 5th gen? There's a Yoshimura slip-on for sale on my local auction site fitted to a 6th gen which I like the look of, but I'm unsure that it will fit. Conversely, have any 6th gen owners fitted a 5th gen specific low-mount pipe? That would also tell me that the two are interchangeable.
