The Nissan Path

I bought an exhaust system, but the company sent me the wrong one and they don't want it back. I have an '04 Pathfinder LE (Platinum Edition) and they sent me the exhaust system for an '05-'08 Pathfinder. The pipe size is different (.5"), but if I bought the adapter, everything should line up, correct? Any thoughts?

I doubt it, the 1997 to 2004 is the unibody and 2005 on Frame, so completely different.
So yes maybe you can MAKE it fit, cut and use adapters, re-weld etc.
IE use the parts and pipes as a kit.

I would think you would have better luck fitting it to an armada or frontier !!
