Chinook Parts and Exhaust?

[trhu]

Hello, I have a 2004 Pathfinder Chinook. I'm wondering if parts are different for the Chinooks or if its just a different finish trim kit from the factory (Ive been looking online for parts and the parts lists are broken down into 'LE' or 'SE'). Also, has anyone done their own exhaust work for their pathy? I'm going to have to replace my exhaust system in the near future. Any help/suggestions are much appreciated. Thanks.
