You can always get some giant billet stacks that bolt straight to the carbs that are covered with some wire mesh... LOL

(talk about top end...)

 

i thought i had seen this somewhere.
in this thread the poster used the 4 short stacks from 2 sets of oem ones cut in half.
once mapped he gain midrange and top end hp

That's definately a better way as opposed to some of the guys on .net that were cutting a section out of the center and epoxing them back together (What I was refering to when I said "cut & paste").

That Dyno graph definately illustrates what I was talking about. There is just over a 3hp at just under 14,000rpm and a overall increase from 13,250rpm to readline, but up to that point it just matches the stock (+ a little here, - a little there - which could be just the variance between two different runs). That it didn't lose any down low susprises me, butnot really. Keep in mind the HRC and Ten Kate V stacks areeven shorter than the stock "short" V stack, I think teh Factory pro is shorter *** well, but not by much. But it definately shows two major things: 1) That there is some additional gains to be made here with some more R&D and flow bench time. 2) Honda got the V stack heights pretty damn good from the factory for a "everyday" rider.

Also some interesting reading on V-stacks from Marc at Factory pro here:
