Gadget said:They do sell the upgraded Y pipe separately. Call TRD direct and they will give you the correct part number for your year truck and then you can order it directly from your local dealer.
It is the same Y pipe, but they cut the flanges off of the end and welded on slip joints that use a big ball type gasket and it is held under constant pressure with some big springs. That upgrade is what saved the TRD headers from being a total POS. With that mod they are the nicest headers you can get for the 5VZ.
Do you know what company makes headers for TRD?
