Just got my upr x today and had a few questions on installing it. The part came with a 2-3 inch long extra piece of pipe that is flared on one side, does anyone know where this piece goes or if it is needed. My second question is will it be easier to go ahead and connect the 2 pieces that go on the driver side header before installing the x itself......or should I installl the header tube first and align up the x pipe then connect it to the rest of the x?
