Abstract
A tube arrangement as described herein can include a first and a second wedge shaped circular tube, or pie cut, that are each defined by a front face and a back face, a minimum face-to-face distance between the front face and the back face that is smaller than a maximum face-to-face distance between the front face and the back face. A plurality of evenly spaced keys is dispersed along the front face of the first pie cut. The keys are engaged with a plurality of evenly spaced facets dispersed along the back face of the second pie cut. A weld seals a joint located between the front face of the first pie cut to the back face of the second pie cut. This arrangement is beneficial for constructing custom shaped exhaust tubes by welding the offset pie cuts as needed.
