Only one I've come across is when Jr Wlson engine-dynoed both (open pipes) on 
a 426-cube stroker Fontana Cleavor. As I remember him telling it, he found a 
mid-range torque increase but lost some 200 rpms at the top of 5th gear. Since 
in ORRs he was looking for top-end, he scrapped the 180s. Jr thouight the 
drop-off came from gas-resistence to flowing through the convolutions and extra 
tube length of the 180s and to this day he still runs 4-into-1. So as usual, 
the answer is, it kinda depends on what specifically you want from your car. 
FWIW- J DeRyke
