I have run a few different pipes with the OS and seems it doesn't like the conical cut headers
makes them run to hot .
I like this pipe the best

i had no problem with temp...my only problem was the poor run time ...the engine was pretty fast...i don't know...maybe it needs readjustment....i've already taken off the one of the two head shim...i hope that will help a bit...thanks...maybe later i'll try the os1040 as well

Hi When you said that you took off one of the 2 head shim, what % of the fuel are you running?

thanks.

Apparently the 1040 is no longer in production. Has anyone heard of a replacement product from OS?

I assume with the new ninjas being OS produced that a swag of new products are on the way, and that the ninja pipes will work with the spec II, but I don't know when these are due?

I dont think it suit Spec II, mugen NR2501 is a short pipe and spec II is a Revy engine I think longer pipe will suit it better
