650sx pipe on 701 sj

[Dustin88]

I read a few posts about using a kawi 650sx pipe on a superjet.

Can anyone expand on this, do you use a factory kawi manifold?

I heard it makes good power and I have a westcoast and Factory 650sx pipe.

you use a coffmans or factory YAMAHA exhaust manifold with the three bolt top pattern then throw that factory 650 pipe on there

So if I get a manifold, how different is a factory 650sx pipe from a limited 701 pipe?
Would it add about the same power?

maybe a little less the 650 chamber is the smallest one off all of them. you can just look for a limited or mod chamber later and put it on your factory head pipe it matches up

Cool thanks, so the factory 650sx head pipe is the same as the 701 head pipe?

I think they are a little different like one is a A head pipe the other is a B. someone else with more knowledge will need to chime in here
