Full radius Ram Tubes

This picture was just too good to leave out....

Race tuned engines use Ram Tubes to increase airflow. The tube is of a tuned length and has a flared "bell" to control turbulence. The cheaper models have a partial roll on the flare, but the best ones have a "full radius" bell.
