ISF Exhaust?
So I was able to test drive a stock ISF today and I noticed that once the car was moving at around 65-75 MPH the exhaust note changes and gets really deep and loud to point where I could feel it in my ears. I'm just wondering what makes this happen and I could get a similar effect with an M3.

The IS-F still has two fake tips. Two of the tips are fake on my Dinan exhaust, who cares.
My guess for the boomy-ness of the IS-F exhaust is that the 8-speed in that car tends to upshift to high gears at lower than ideal speeds which puts you on the borderline of lugging the car.
