Using slp prox 600 twins with a 600HO?

[zach13]

I am building a 2002 Pro X 440 into a 600 H.O. out of a 06 switchback. I am not worried about the exact fitment of the pipes. what i am worried about is the way the pipes will work with the motor with the difference in valving and flow of the motor. So has anybody ran these pipes with a 600 ho?

Pipes

Not sure if it helps but I run the SLP Prox Twins on my Carl's Cycle 660 and they work fine. It's in a ProX chassis and those are the only pipes for a 600 in a ProX chassis that they built. I would have liked to run the single but it wouldn't fit. SLP may be able to give you more info.
