So the new Akrapovic slip on for the 2018-19 GT3RS doesn't seem to fit the 2016 Gt3RS as it's not cross referenced on the Akrapovic website. All the other rear center deletes (e.g. GMG, Sharkwerks, Soul) fit 991 GT3RS's from 2014-2019. Has anyone here bought one of these and have some understanding about this. It doesn't seem to make sense.
