yes sir... ... . i hate to be overly needy..... but i was hoping that i could find a y that would either divert the flow one way or the other. the link you sent me would work great but it would require two of them which gets kinda spendy. if that's what it takes and thats the best option then so be it. but if i can accomplish the same thing for less that would be optimal. is it possible that with two of these (one for each side of the y pipe) so that one could be open and one completely shut off it could act as an exhaust brake. not for us while driving etc, but just for warming the truck up when its cold out?
