250-500cc Do I gain anything from any aftermkt pipe for the 300?

Got an 09 300 and was contemplating a pipe. Just the 300's power is so perfect now that I didn't want to mess it up. I kind of would like more mid and top without losing low end. I was thinking about the gnarly but was told you lose top end. Any recommendations?

I recommend that you ride the piss out of it , I put a Dep on mine and it wasn't much different.

For what it's worth, I put a Gnarly on my 250 and it helped the top a lot and made the mid smoother and easier to ride but keeping the same hard pull in the mid. I thought it was worth it but only did it because I smashed the stock pipe, now I'm glad I did.

The Gnarly pipes are much harder to dent than a stocker that's for sure.

I agree with troffer88. Ride the shit out of it until it breaks. Then replace it. I have an 09 300 and after I smashed my stock pipe went with the PC system. I love it, but wouldn't spend the change until the stocker is smashed.
as a side note, i didn't care for the gnarly on my yz250 as it killed the top end. Boosted the low and mid awesome, but top end was crap afterwards. So I went with an FMF Fatty, which was sweet. Sounds like it is different on this bike from other peoples posts, but with that in mind, I got a PC...

I hear good things about Pro Circuit pipes and silencers. If I was going to PC then I would go with the Platinum 2 pipes. Sort of like a FMF Gnarly. Extra Heavy Duty.

I was satisfied with my stock pipe also, bike ran great and had power everywhere but it was the weakest link and needed to be replaced. I now have the FMF gnarly and the bike seems to have more low-mid power, it seems slightly flat on top though. I'm running the stock silencer with no problems also.

The Gnarly fits particularly well on the Husky and has a better, cleaner power band than stock. It is a nice package and strangely, better done than the Gnarly is on bikes like the KTM 250/200.

I also run a DEP that works well on the bottom, but pulls harder and longer on top. Not as well sorted a fit as the Gnarly. I drag raced my bud on his 2011 KTM 300XC with a 6spd. We both had one tooth extra on the CS sprocket and I was running the DEP and a Motorsportz Keihin. The Husky gave up nothing to the KTM. We were surprised.

Habitually, the WR300 easy outpull the Katoom... not close on pavement.

Sounds like i would get better money spent on shane watts training course next time he comes to town if i want more speed, lol

My WR is a 250 and it ran right with his 2011 KTM 300!
