To really do it right, I recall RARE mentioning a 90 degree bend X over, (at the time, he showed me a 3" pipe for a drag car - 90 degree bend inlet) which allows the pipes to be properly positioned without having to drop the brace on verts. You want this as close to the front of the car as possible. The oval x over is really the best case for clearance without giving up air flow volume. I don't know if he went ahead a made them for a 2.5 system?
