Left bend_VS_right bend pipe

has anyone on this site seen a "crankenstein" banshee? its the banshee bottum end with snowmobile jugs turned around backwards so the carbs are out front where the pipes would normally be and the pipes come straight out the back where the carbs would normally be... this is the best example that its doesn't matter the bend left, right, up, down, these pipes are have no bend what so ever and untill about 2000 they were the fastest drag bikes around
 
i guess tha depends on who told you what they told you... it's wrong.. research how a 2 stroke expansion chamber works..
