What makes you think the intake tube is restrictive?

I'm not convinced it is, it just seems like it might be. The added
length, and the two near 90 degree bends in it. Without actually
measuring one, it looks to me like a longer path, and possibly more
restrctive.

If I had one in front of me to compare with the stock set up I might
have all my doubts disappear.

Has anyone here ever dynoed the difference in HP claimed versus actual?
