Hi Wally
I have the auto version so unable to comment re the manual version. I also don’t have the sports exhaust but would say that I (or at least the car, I wouldn’t dare comment on personal issues) have pops in both Sport and Sport + mode.
I only have the speakers fitted ( and only hear the rear ones by the back shelf) and my iPhone connects via Bluetooth so I can hear playlists/satnav as required. I think it’s worth it personally although in hindsight I would get something done about the lack of volume out the front/door speakers
Best wishes
