My engine is bone stock minus the PC pipe and Turbine Core Silencer. I felt a difference throughout the rpm range and it wasn't so choppy. I plan to get the 1/4" spacer from JFab eventually.

My 1/8th inch spacer didn't affect the early sign off. It actually made it less noticeable. Maybe it's just enough to get the reeds out of the turbulence and smooth it out without effecting the top end? I primarily ride open fields and mx track with a little bit of woods riding at my parents on 12 ft wide trails.

I ended up getting a stock pipe and keeping the FMF Gnarly.  I'll use the the FMF for the motocross track and the stock one for the sand pits.

Now I just have to play around with the jets.
