FOr the B16 the new RMF Replica/KiddRacing header is best in terms of ground clearance and it is the best on power.
The Hytech Replica i sell the small tube and big tube, the smal tube is what you want, it is cheaper, but it doesnt make the same power an the ground clearance kinda sucks on a b16.
We have 2 of what he sells VERY HAPPY w/results I might ad.
