Same cones as the street pipes, but with 1" shorter head pipes and as I remember, 7/8" OD, 3/4" ID stingers. They're really made for going 1/4 mile and letting off the gas before trouble starts. $300 is indeed a great price.

It's one way to make the pipes tune at a higher RPM.

I get about a 250rpm shift with a 25mm length change with Vannik.

I bet the tiny stingers raise it some more, compared to the street version.

Yup, I agree.
I haven't played much with stinger size, I like the conservative approach on that front!
I definitely wouldn't run 3/4" ID stingers on a street H2 though, that size is better suited for a 400 imo

Maybe if the H2 was running about 15 PSI compression and made no Hp

The small stingers make great HP for a short time, but tend to make pistons hot if run wide open very long.
