986 BOXSTER/S (1997-2004)

All our exhaust tubing is state-of-the-art Mandrel bent. Mandrel bent means the tubing is laid inside the metal mold before it is shaped to its size. With mandrel bending there is hardly any distortion. Normally, when a tube is bent, it becomes smaller in the bent area. With mandrel bending the inner tube dimension stays the same to get maximum strength and stability.

Don't settle for less!
