No it is not a Gnarly.
It's a GP/XC pipe on the parts fiche for the XC.

Yes it is a gnarly. I have both pipes and they are identical I?ve taken measurements around the chamber in several different spots on both pipes. The GasGas pipe is the exact same as the gnarly except it says GasGas on the side. They use the same mold. I called FMF and asked them and they confirmed it as the gnarly pipe.

That's odd, The FMF Gnarly I bought from FMF definitely isn't the same shape & weight as the FMF marked pipe on my XC (that has the same fiche part number as the GP.)
I was told by the FMF rep that the only way to get the actual pipe that came on my XC was to buy it through GasGas.

I want to take the "that's odd" part of that comment back.
Actually It doesn't surprise me much at all thinking back and realizing that I've seen XC bikes on the show room floor with pipes that looked like the EC model and EC bikes on another dealer's floor that had FMF marked pipes that appeared to be the same as the one on my XC . . .

I think maybe the only way to get the one marked ?FMF GasGas? is through a dealer. I bent mine last summer and wanted to get a replacement so I started calling dealers and looking online. None of them had or could get me the stock pipe but they all had or could order the FMF gnarly or fatty. I started thinking it would be expensive for both FMF and GasGas for them to mold a brand new style of pipe specifically for a handful of GasGas bikes. This had me curious so that?s when I called FMF and the guy I talked to told me it was a gnarly. I ordered one and it is identical to the stock pipe besides the marking on the side. I have also read another comment online about a guy who ordered a gnarly pipe and it was different than the stock pipe on his XC. So I?m not sure exactly what could be going on. I will take some pictures with a caliper measuring the stock pipe and gnarly pipe side by side and post them to this thread later.

Being that my Factory XC pipe is physically different from the FMF Gnaryl I bought I'm pretty sure that GG is doing the same thing as KTM/Husky regarding their brand stamped pipe in that it's a thick walled Fatty shaped pipe.
The Austrians call their heavy walled, Fatty shaped expansion chambers the "Factory" pipe. https://www.rockymountainatvmc.com/parts/husqvarna-fmf-factory-pipe-p?v=14999
Not to be confused with the "FMF Factory Fatty" which is a "works" finish, thin walled Fatty.
Honestly, I'm getting the vibe that some GG bikes are being shipped with what ever they can grab off the stock shelf when parts are delayed or damaged at one point of shipping or another.
If that's the issue I get it: GG and the dealers gotta do what they gotta do to get units on the floor and out the door.

The XC pipe looks identical to the Gnarly when it’s laying on the floor. They have VERY different power characteristics though. I would have bet a paycheck that they are the same until I rode with the Gnarly. It has noticeably more bottom end and signs off much earlier than the stock XC pipe.

Yep, same experience. Unfortunately I bought the Gnarly after I read an internet post saying it was the same thing. Another $225 lesson learned the hard way. Again. It's a recurring theme I'm having after switching to this bike. About the good thing, imo, about the Austrian machines is that they are so prevalent that people have already worked this sort of stuff out.
Interesting. I put an RK Tek head on mine at the same time as the new pipe so I couldn?t make a comparison between the pipes. If they look identical and measure the exact same how can they be different? Different thickness maybe?

I haven't taken any meaningful measurements but the pipe mounting tab on my XC pipe and the tab on the Gnarly I bought from FMF don't line up on the same weld seam of their expansion chambers. The tabs are also of different designs. Those are clues I'm using that the pipes aren't the same.
