Great pipe. Just a tip here from my tuning with one....they like to be long. 11-3/4\" to 12\" from center of flange straight back to the 'weld'.

so by flange i gess you guys mesureing from the eaust water head oring flange im gessing. also . have i got it right , that shorter pipe is more torque and longer pipe is more revs , and have pipe able to tune from 11-1/2 in to 13 in lenth from head of motor to senter cone of pipe. ive got mine set ruffly at 12 or 12&1/2....

By flange we mean the water-cooled flange that bolts to the engine exhaust port.

Shorter = tunes at higher rpm Longer = tunes at lower RPM (generally giving more TQ)

A better way to measure is to follow the center line of the header and pipe starting at the outside face of the flange. You should be in the 12.5 to 12 3/4 range. This is a good starting point for the CC steel pipe.
