The loud popping mode with valves opened makes the Boxster sound like a lawn mower. So far, the SwitchPath exhaust sounds the best to me with its low growl. Everything else seems high pitched to my ears.
FYI
I have the sports exhaust option on my Cayman S. Maybe it's the quality of my laptop speakers - but after watching the video, I am having a hard time distinguishing the difference between the sound of the OE exhaust and the sound of the aftermarket systems.
How much deeper do the aftermarket systems sound in real life compared to the OE sports exhaust when Sport mode is activated? Is it a significant difference?
