Just installed the zr9 pipe mod on my stock 06 900efi...done by BMP. Pulls very nicely mid- low..not a whole lot a diff after 80-90 mph.
Was running over 100 mph on long(1/4 mile or more) pulls over snow, stay w/ any stock or lightly modded 700 Fcats or F1000 plugs look nice..tan lt, brown.
Running @ 7500 on tach w/ 85 gr Daltons.
..have any one w/ this mod seen a need for a RPM over 7500 w/ that pipe mod for MAX results..

Thanx... Bob

I'd run the RPM Bikeman suggested, they should have dyno tested the setup during R&D. The pipe mod changes the stinger on the stock pipe which should not have much effect on the RPM the pipe was originally meant to operate at.

You could try running higher RPM's to see if it's faster (your tach may be a couple hundred RPM off) it won't hurt anything but your HP. Maybe you'll get lucky and find that little extra oompf!
