Pipe length is the distance from the exhaust side of the piston to the start of the divergent (first) cone. On straight, 30°, and 90° bend pipes the first cone does not start at the first weld. The first cone extends into the flex cup ~1/2". If you measure to the end of the flex/connector tube before installing the pipe, you will have the correct pipe length as the end of the flex stops against the first cone.
