Ram bending is often called crush bending. It uses a female die to match the tube diameter with the angle of bend radius required. The tube is simply hydraulically drawn over the die. In the process, the outside of the bend stretches to make the outer wall thinner. At the same time, the inside of the bend compresses, featuring a crushed area that creates an unround condition within the bend radius. While this may be acceptable for passenger cars’ exhaust systems, it’s not acceptable for a performance system because tube restrictions are to be avoided.
