FMF Powercore 2 Silencer:

  • The sleeve of the Powercore 2 silencer is constructed from extruded aluminum to provide a lightweight design. FMF incorporated a tuned perforated core for exceptional performance.

Sounds great...

But it doesn't deliver on performance. I bough this for my son's pw50 and it really does make it sound like a "real " dirtbike, but that's it. I'm a honda/pro circuit guy, but on the PW50 there were no noticeable performance gains. The OEM parts/equipment are designed to make the machines run at a standard rate. Be careful of buYing into the hype of aftermarket parts. While many do affect performance, many are gimmicks. This is a gimmicj.

FMF ALL THE WAY!!!!

I'm an FMF guy. always liked the performance and sound of it. Just wish FMF could get there coating on better somehow. First time out riding and then wash, it started to get rust spots on the pipe. Overall still satisfied with it.

Best pipe and silencer ever

Just installed the new FMF "Fatty" pipe and silencer on my 04 YZ250 and it was a perfect fit. I can tell an immediate difference in the low end and mid as it rips. This was a replacement for the Pro Circuit pipe that constantly cracked and had to be rewelded. Poor craftsmanship on PC's part

Wakes up the RM125

I added this combo to my sons 06 RM125. I also added a VForce3 reed system and it really wakes up the bike throughout the power band. His practice bike has the Works finish which can be a bit of work to keep looking good so I went with the platinum finish this time. FMF seems to hold up to rocks well without denting.

Adds good power with a longer lasting pipe

FMF always makes the best quality pipes in my opinion. I got this pipe a couple of years back for a yz250 and it runs great. With much stronger metal than the stock pipe. Always have bought from motosport, always will.

LOTS of rust inside the pipe.

I was very excited to get my pipe and silencer. But when I looked inside my pipe to see how it was and the conditions, I found LOTS of rust... It may not effect the bike, but it's something I would not like to see.

Pucker Factor!

Most aftermarket exhausts I upgrade from stock doesn??t give you a noticeable feel of increased performance. However, the FMF pipe and silencer combo I chose took approx. 5 min to install. I then test rode my 2013 Yamaha YZ250 for a few min. WOW, what a difference! The stock exhaust raised the front wheel in first and second land sometimes in third. The FMF raised in all gears and increase the pucker factor. Oh yeah, lighter than stock.

Best pipe for me?
I race motocross and our tracks are a little tighter. Lots of corners and that type of stuff. I have a 2014 150sx. I feel like its got enough bottom end power. I need a little more mid range power I think. What pipe would be recommended?
MotoSport Staff Expert

I would recommend the Fatty pipe and Powercore 2 Silencer. The Fatty pipes are designed to give the engine an all around power increase. We are not drastically altering the power band of the bike. This pipe will appeal to most people that are happy with the stock power band and just looking for more useable power everywhere. A Powercore 2 silencer will give your bike increased throttle response, a lighter and higher quality silencer with that factory look and sound. The Shorty will give you even more throttle response and low end power. Because it's smaller you'll see even more weight savings and a louder sound level. Also, feel free to give us a call at 888-676-8853 and we would be happy to help you out with your order.

I have a 2015 ktm 85sx and ride in tighter tracks. I need more bottom end so would the power core work better or the shorty?
Expert MotoSport Staff

MotoSportExpert
For the tighter tracks you would want to go with the shorty for more bottom end. The FMF Powercore 2 Shorty silencer has a shortened inner core length and canister. The shorter overall length allows for the exhaust gases to exit quicker giving the Powercore 2 Shorty silencer better performance on the bottom to mid range of the power band.

This would be a great pipe and silencer combo for your 1997 Honda CR250. The combo would come with one silencer, some models you have the choice of the standard powercore 2 or the powercore 2 shorty. The shorty is not available for your 97 CR250. Feel free to give us a call at 888-676-8853 and we would be happy to help you out with your order.

I have a 99 kx80, what would you recommend out of the fatty pipe with the shorty, or the fatty pipe and the turbinecore 2 arrestor?
Expert MotoSport Staff
Over 6 months ago
MotoSportExpert
That would depend on what kind of riding you are doing and what kind of performance gains you are looking for. If you are riding offroad where a spark arrestor is required you would want to go with the Turbinecore 2 arrestor. For tighter motocross tracks the shorty would be a good choice. Feel free to give us a call at 888-676-8853 and we would be happy to help you out with your order.

Oil leaking out of exhaust where it meets the engine? need help?
I have a 98 cr 125 and oil keeps leaking out of the exhaust where the fatty pipe meets up with the engine. I was wondering if i need to buy some sort of gasket or just new springs and maybe use some high temp silicone to stop the leak. I hope to fix it soon its definitely getting caked on the pipe and engine pretty good.
