Best Flattrack pipe for 330R

[Scott270R]

Hey I just wanted to get some feedback from those of you who have raced flattrack before. I have a 330 bolt on kit with few different pipes they are as follows:

CT national midrange pipe
FMF H-49
FMF Fatty SST
Paul Turner "Race 2003"
LRD Adjustable 250 team "B"

My question is, for racing on a 1/4 mile clay oval, which would work best and why? I want it to be a holeshot king and have the power where it will work best. Oh yeah and what gearing/tires are you using as well.

Thanks in advance I plan on racing in a couple weeks I just wanted to here from those who know.
