F birds "Y" pipe is interesting, reminds of the Tri Y headers I dyno'ed the Tri Ys! The increase in hp and torq was quite a bit more then street headers and fell just short of tuned competition headers till they entered higher rpms! over 5500rs! I guess that works on the same principle for scavenging!

I never ran shorty's either.
