RPM range for peak HP on '07 M8 with single pipe?

[SnowBigDeal]

I'm new to Arctic Cat this year. I've always been a Polaris guy until now. We'll see how it goes, I just picked up an '07 M8. The only "engine" mods currently are:
Speedwerx Single Pipe & Can
Boondockers Fuel Controller.

Question: For a single Pipe & Can, what is the RPM range I want to be in for peak Horsepower? Can anyone point me to a dyno chart they find to be reasonably accurate with this setup?

I need to get my clutching set right and would like to know what I am shooting for before I start tweaking.

8000 rpm is the target # for the speedwerx pipe set.

I Have the SLP single with y-pipe and can on my 07 and it performs best at 8100.

On my completely stock machine (OEM pipe and can) max horsepower was at 7550 RPM.
