Hi. I just had PSE installed on my 2018 718 base PDK Cayman. I’m hearing a sound that I haven’t heard with the windows up. We had nice weather today so I drove around the neighborhood only up to about 45 to 50 mph. As I was driving I noticed what sounded like a spooling (woosh) sound as I accelerate. I’m not sure if that’s normal. Is it possible that that is a turbo sound? It’s my first turbo. Inside the car, I don’t hear anything except for a nice exhaust note that is meaner than it was before I installed PSE. With the windows down, I find that spooling sound to be kind of annoying. Is this a normal sound? Do other people hear this? It could even be just wind, but I don’t think so, Considering I just put down $4000 for this exhaust, I want to make sure that nothing is wrong.
