yea, i heard that the piping has 2 sections and for each section, the diameter is different. Therefore, when the diameter becomes narrower, more air can be compressed into the manifold.....or some s*it like that......

I dunno if i'll pay the extra for a V2 tho.....i mean intakes are something that gives us maybe 2-3 whp gain and why spend the extra 50 dollars on something that wont affect anything much? Just my $0.02
