Is the FMF Gnarly really that "Gnarly?"

My 18 year old has wasted the OEM pipe on his 300 XC in all of a whole year. Kid is just hard on stuff. So I'm wondering if I/he should try a FMF Gnarly. My 15 year old has both the stocker and the Gnarly for his 200 XC/W and the 18 ga. steel sure seems more stout. Thought about a pipe guard but it's near the price of a new pipe anyway. Any ideas?

I run mine without a guard and yes, they are pretty darn tough.:thumbsup:

the stock pipe is paper thin, anything aftermarket will hold up better. the gnarly is just thicker than say the fatty, which is thicker than stock.
i crushed mine in about 3 months, if you son got a year out of it, hes better than me. i fixed mine 3x over before deciding to get the Fatty, i haven't dented it yet.

I got two months out of the stocker. Now I run a Gnarly and a carbon fiber guard, two years and no real damage. I have to pull it off and flex it back into shape every now and then but no crush damage.

PC platinum is a beefy pipe, but big I know the Gnarly is a smaller pipe and tuck in nice.

Well there's your problem :lol:

Make him buy his own parts and the damage will quickly diminish once he figures out how much his abuse costs him :thumbsup:

Im still running the stock pipe but would like a Gnarly also. If for nothing else than to keep the stock as a spare.

I cant see how people like Gnarlys..all bottom end with no top end or overrev. Guess different strokes for different folks..heaps better pipes out there imo.

when you ride mostly steep,tight,high altitude mountain singletrack like i do, the gnarly low end is priceless. a few times each year i open it up in desert or more open terrain and it scoots along at a fast enough clip that it doesnt matter to me....what does it lose 5 mph? big deal.

There with you 100%.


I have a gnarly and its tough. I flipped over backwards on the road and my bike bounced pretty good. The pipe had minor asphalt scuffs and a minor indentation. Not bad imo

The Gnarly is not made for top end speed, if you want that get a Fatty.:thumbsup:

Yeah, I agree with kids pulling their own weight $$ wise. He's been paying for his own bikes since 11 years old. Now that we all ride "big boy" rides (all four of the family including mom rides 250+ scoots) we share a lot so I go half on all access. and repairs. Kinda nice to have 6+bikes in the stall to choose from:thumbsup: :thumbsup:

Also, he races pro class so it's balls to the walls. Little different for us "age group" racers:ride: :ride:

+3 I am running a gnarly and it is strong but I don't care for the performance. I think it makes the bike a little stinkbuggish (is that a word?).

I think the Fatty would also be a good choice. It you run the SST doesn't that have a different diameter end that doesn't work so well with the stock silencer?

Wondering. Has anybody ran the KTM hard parts pipe built for KTM by FMF? What are they like? I'd only buy a gnarly for the 18ga steel not for the power curve. 300s are like a Duramax on 2 wheels. I don't really see the need for more low end grunt...plenty there already.

I used to have an 02 YZ250 with both the stocker and an SST. Amazing how the SST smoothed out the power and the stocker was a beast off the bottom. And the SST bolts right up without the need for the special SA that other SST pipes need.

What about a PC pipe? Anybody got experience with those?

Colorado trails would change your perception a bit. The Gnarly is an excellent choice for technical high mountain single track. :thumbsup:

I have a Gnarly on my 250 EXC and I like it. It has a few minor dings, but overall has been a tough pipe. I am getting ready to order a new one ( the dings bother me, I am anal... ) if anyone wants my old one I would sell it cheap.

These guys do nice work: http://www.piperepair.com/ It might be worthwhile to send it to them versus replacing it.

Im still in the poor 12 yr old son stage so I pay plenty for his bike abuse. But I make sure to bitch plenty so he knows his abuse is costing me money :lol:

AMEN, brother! not for everyone, low end for mountain riding ! there is a killer trail here in WA. that is in Gifford Pinchot Nat. forest :worthy: called Bishops ridge. it is SEVEN miles of 35 to 45 degree angle uphill all the way. wouldn't be too bad if not for the bowling ball sized rocks with a few softballs thrown in for most of the way. gnarly and trials tire baby!:busted:
