SLP twin pipes on a 600ho

Hey guys,
I really want to run slp twin pipes from a 2006 mod on my 2008 iqrr 600ho...
I've done some research and this is what I have come up with for a clutch set up..

Primary - 58g weights almond/red spring
secondary - 66/44/.46 helix with black spring

The motor is completely stock. gearing is 22/43. I ride 0-1500ft.

For jetting I am running 400 main, 40 pilot, and .9 air pilot.. I will bump that main up a bit just for testing purposes...

how do you think this will run? also, at what rpm does the slp twins run at? do you have any tips you would like to share?? pm me if so please!!

I don't need anyone to tell me to sell these pipes and buy a dynoport single...

thanks a lot!
