If they are used with a 2.5" system they are nearly 10% smaller in diameter. It ends up being a 2.2" throttle body. Is it because the Plenum just can't accept a 63mm opening without causing problems?
----------------------------------- A man once asked me if I took certain things seriously. I guess I made it seem like I didn't, but I do. Now people tell me I take things too seriously, but they don't understand. They don't care either. I don't feel they respect or understand what I'm trying to achieve. Perhaps it is their own sense of failure that is trying to sustain and validate itself.
