2 into 1 exhaust jetting?

[trex banshee]

Just for shits and grins i put a motofast 2 into 1 pipe on my stock bike just to see how it would run. I had been running rockets on it with 25 pilots and 310 mains, stock needles in the middle, and no air box. My question is what is a ballpark figure for jetting with this pipe. My elevation is about 900 feet.

 

I'd figure the jetting for the rockets would be way rich, but i've never jetted for 2 into 1 before? :biggrin:

I dont know, it should be a little rich, but I dont have stock carbs on my bike.
