Looks like the MOCO put the O2 sensors in different spots on stock head pipes. Anybody move the sensors on stock head pipe? Maybe equal distance from exh port? Asking as I do not know ....... Lengthen rear pipe to equal out length in a defatted head pipe. Choked down size from head pipes to match rear muffler a bit for smoother transition .....almost like a merg collector. I'll buy a good header eventually . But had a to tig a bunch of stailnless other day and and extra header laying around.
Guess Not..,,
