Fair comment Laurence.
Regarding the 718 sound, I am still considering the FVD Brombacher Sport Muffler, Export Version, with exhaust valve. A bit of a mouthful! A photo of the cat-back system is attached. You will notice that this exhaust retains the unequal length headers, it replaces the standard PSE and is only available for PDK gearbox 718's. I've been told by FVD that the Export Version with the valve open is quite loud, >100db, too loud in fact for Germany's streets. The current sound of the PSE is slightly deeper and throatier than the standard exhaust, but still requires some work on the raspy nature of the sound at certain revs. Regarding the sound, I'm in the "you get used to it" camp. At higher revs it honestly sounds fine.
Intersting to read the car mag testers reports on the new 718 GTS. Even Andrew Frankel stated that the PSE on the 718 GTS he recently tested, seemed "less farty" than on the "S" model. Maybe Porsche are refining this sound, and like the EPS development, will eventually achieve an acceptable result.
