I have a '04 Desert Runner 6 cyl Frontier, it just started to develop an exhaust leak at the bracket pipe that connects the muffler system to the Y-Pipe. The problem is the Frontier microfiche shows the y-pipe as having a flange to mate to the muffler system but it doesn't , it really uses this bracket pipe. The parts dept. ordered in the y-pipe to see if it came with it, even though it doesnt show in the fiche, they also ordered the bracket they saw in the fiche. THe y-pipe came but no flange, its like the one on my truck and needs this 'bracket pipe' part to mate to the muffler system. They are sending a query to Nissan to see whats up, I came here. Anyone know this part? Anyone who changed or upgraded want to sell their unwanted part?
