But really, elaborate on the whistle.
I can't explain it that well. I've tried to come up with what I'm going to say, and still haven't decided on an intelligent definition. It is turbo whistle, but like I said, it is profound on stock turbo's and aftermarket turbo's. I have a friend that has a stock forester with a catless dp, and upon start up you can hear his turbo whistle the same as a friend who has a built block with a FP Green. However, I have a friend who has a catted DP and an AMR T60, and his sounds the same as the guys with catless dp's. I'll try to send you a video later that demonstrates the sound.
