Identify FMF Gnarly Pipe, and jet Question

I just bought a used FMF gnarly pipe on Ebay. It arrived and is in pretty good shape. I'm replacing Stock so either desert or Woods would be a great improvement.

The Seller Thinks they remember it being the woods pipe but wasn't sure and I dont' see any identifiers on it? Is there a way to tell the difference?

Secondly Should I plan on rejetting after adding just the pipe? or is the change enough to require it? (I need to double Check RB's Jetting anyway since it does have a bog)

Thanks Ya'll

Have a look on the FMF website.
They show 2 different part numbers (on one of the mounting tabs), and also the correct jetting.
If I recall, the desert pipe was the larger, and about 15" circumference at it's largest section.

Other people here have more experience with it than me. I'm sure they'll chime in.

Well it says 020056 Which the FMF site says is the Desert pipe instead of the woods pipe! the ebay description said they thought it was woods. SO I'm kind of bummed since coming off of of 4 strokes I kept stalling the KDX on hills because I didn't keep the RPM's up and was looking forward to the grunt in the woods.

But after a search I am seeing many of you enjoy the desert pipe in the woods? Well its here so I'll give it a go!
