Ive been having trouble finding or building a y pipe for my flowtech headers (2 1/2 in collectors) and was wondering if anybody knew anything about the flowtech y pipe and hedmans y pipe (PN 17470)... my plan is to figure out the pipe sizes where they meet the cat and then the collector size. If worse comes to worse i plan on cutting of the collectors of maybe the henman pipe and welding new collecctors on that will match the angle of my headers....if anybody could help me please do...thanks.
