Why is mandrel bent tubing better?
Mandrel bent tubing has a uniform diameter throughout the bend, a 2.5″ mandrel bend would be 2.5″ all the way through. This keep performance up and exhaust flow high and efficient, maximizing the performance potential of the system. A crush bent pipe is literally crushed into a bend, making the diameter smaller where the bend is made. A typical 2.5″ crush-bent pipe could only be 2″ in diameter (or even less!) at the bend. A picture of a crush bent (left) and mandrel bent (right) pipe is shown below.
