I just purchased a used upr o/r x pipe it came off a 2004 gt and I put it on a 2003 gt and it doesn't line up quite right, it isn't up close to the car as it should be and it also has a slight leak. I was told it was the same pipe to fit a 2003, but on the upr website they list a different part number for the 04 as opposed to the 03. I also was told it didn't come with a gasket when it was purchased new. I have it I should use one on the passenger side, if so does anyone know a part number and where to get one. I also was told it was a good idea to change the manifold studs on the driver side to ones that don't have a shoulder, does anyone have any info on the part number and where to get them.
