Hi there. Kieran your option sounds very good. Do you have any posts at all with the sound recorded? When I have listened to various GSF exhaust alternatives, they all sound fairly similar once the initial start up excitement is over. I Am also wondering about some exhaust enhancement but also very much aware that when I had my really quite loud Porsche Panamera GTS, I tended to turn the exhaust “off” most of the time as it was just too loud for an old git like me!
