250-500cc Toughest pipe for a WR300 2010 ?

Hi all,
what is the toughest pipe I can buy for a WR300 2010 ?
I'm with the stock one and lightly touched a side wall and it all bent over, I bent it back a little with my boots to avoid touching the radiator hoses .... Seems like a really soft and thin steel to me...

I was thinking of getting some more ruggered pipe, that can handle some impacts better without bending al over...
First idea I had was the FMF Gnarly as they say it is made of thicker steel and can handle rocks better, but reading in forums gave me the conclusion that this seem not to be the case and they are also pretty weak...

I don't know any other brands known to be heavier, thicker, more robust... I think the majority of pipes are designed with weight savings in mind and not for being more robust...


By the way, I want to put some protection on the pipe but don't know what to do, those aluminium or carbon protectors I think only protect for little impacts but cannot avoid the entire pipe to bend over (my problem was the first turn of the pipe bending and touching the radiator hose..... A thin carbon protector had not avoided that I think.

I like the HYDE pipe protector but they don't seem to produce it any more for the 300 2010

I've got the Pro Circuit P2 on my bike and it's tough as heck. Unfortunately, they don't make it anymore and if you do find one, you have to purchase a Pro Circuit silencer since the pipe doesn't work with the OEM muffler.

I suspect that they're all about the same as far as strength. I have an FMF on my bike, it's been fine, although it does have the usual dents in it from falling over on rocks, etc. I do not run a protector, I'll just blow the dents out every season or two.

I'd buy a pipe that meets your power delivery characteristics, put a guard on it, and just deal with whatever comes your way.

I run a Gnarly with a P3 carbon guard and have hit some serious stuff and just scratch the guard.
I do think the gnarly is a tougher pipe than stock. I have an HGS pipe on my other bike and it dents as easy as stock, maybe easier.
The only other option is to just not hit big rocks and stuff with your pipe lol.

Thanks for your answers, I've read that the OEM catalytic pipe is stronger than the OEM 'racing' pipe, I have to pass the technical inspection today and if it do pass with the racing pipe I will open up the Catalytic pipe and empty it... I have also read that this pipe is better for low-end....

Regards.

The FMF Gnarly without question is tougher than stock. A lot tougher. Add an aluminum protector and you should be good. The FMF is a great pipe if you're looking for
more low end torque. Turns the 300 into a chuggernaut yet still has the hard hit when it gets up there. I'm really happy with it's performance.

Get over it and buy another pipe and keep one blown out for the next race. You need two pipes trust me, if you race. No pipe is strong, it's thin crap.

Exactly.

Pro Circuit is stronger than FMF. FMF is about on par with stock. DEP is weaker than stock.

DEP gives the best engine characteristics. Pro Circuit is too pipey. Stock is best for the extreme gnarly.


I have 2 stock, 1 Husky branded Pro Circuit, 1 DEP. After being burnt by FMF on other bikes, I'll never go back to them for an expansion chamber, though I do like their spark arrestors.

How do you know the brand behind the stock pipes ? My stock pipe is different than the one from a mate with the same bike and year... His pipe seems stronger and has different soldering marks...

Technical inspection passed, I will empty the stock catalytic exhaust if I get time and try that pipe next.


Regards.
