I remember reading a thread in the club lexus vendor section where RR Racing mentioned they were going to start looking at a 3 inch dual exhaust for the ISF and assess it. A few people got excited about it knowing the effort RR puts into development and testing. This was after the supercharger release. This was a few months ago. Haven't heard about it in a while.
