that is the "official" dose pipe, basically its a straight throuhg pipe with NO Filter, just a bit of mesh to stop big things from gettn in, more air means more flutter. according to wogs newai.......
lol wat kind of question is that man? alot of things are intended to be there, for example stock ECUs but do we listen? no why? for the pursuit of happiness (lol i just watched the movie its purty good)
the reason why stock BOVs are removed or blocked is
because it leaks
because it sounds shit
because its a cheap alt to buying a $600 BOV which sounds shiet newai
there are heaps of reasons and the majoirty of us try it at one stage, i gotta say its "sick" lol
if u didnt realize alot of big name companies demo cars do this, HKS for example, their 600hp r34 GTR runs no BOV.
i know the title says HKS SSQV but you know how idiots r
this is how it works
more boost = higher pitched
more air = the longer the flutter
diameter of the pipe = time of burtsts
