Actually I think you are right, I took a quick look at RHD japan and it looks like many exhausts are indeed 3.5", so perhaps more then I initially expected have 3.5" on their GTR`s. I still think 3" would work for you, have better ground clearance if that matters and have less noise. But you would gain power with 3.5", so perhaps a better rear silencer on the HKS silent power is an option? The HKS rear silencer is anything but silent (I have used it as a custom silencer on cars before, and it is LOUD).
