Just picked up a CPO 2018 CGTS 6M, and after having never done this on a 2.0 cayman, decided to try it, after reading the Beowulf sized thread here.
My ears have admittedly been pounded into submission by listening to Led Zeppelin for 42 of my 52 years, but the difference, to me, was startling. I absolutely hear the exhaust and engine better, and the “air cooled” type whine at low speeds reminds me of my just traded 911 in a small way.
An added bonus- my wife said my voice was 10 times clearer on the bluetooth connection, although unfortunately, now that she can clearly hear what I have to say, she is seeking a good divorce lawyer...
THANK YOU to all for your reviews and development of this thread. I’m a chicken, and would not have done this without this mountain of info...
