FMF is the only pipe to get.

Installed on my CRF 250X. Now it sounds great and there is definitely a noticeable power improvement.

Good Product

Replaced my stock exhaust on my CRF250X with this unit. Good sound, seems to have better power. Thought it would be lighter in mass, seems to weigh about the same as stock, this being my only complaint.

I put this header on with the FMF TI Powercore on a 06 yz250f and it was great. Much more power throughout the rpm range. Installed super easy and woke the bike up

Best bang for your buck!

i bought this exhaust for my 2011 honda crf450r. the biggest change was the sound. It has a much deeper and full sound and man is it loud!! also i noticed more top end and slightly faster reving. It is also a very nice looking pipe. i love the blue color and the simple flowing shape. overall this is a great slip-on at the right price!

Good slip-on

Purchased for my 07 YZ250f. Easy to install. Very noticeable power gain. Doesn't quite look Yama blue as the pics show. Has more of a really light sky blue tint. Stickers are peeling off after 1st wash. Overall not bad for the price. Nice power gain and great sound.

What jetting do I have to do with my bike?
I have a 2004 crf250r and I was wondering what jetting I have to do with it?

Normally when installing a slip-on only minor jetting changes are needed, if any at all. If your bike is currently jetted properly you will likely not have to make any changes after installing this slip-on. I would recommend installing the exhaust and riding the bike to see how it is running then tuning your carburetor from there if necessary.

I have a 2013 CRF250R. What is the difference in power with the powercore vs the rct 4.1?
Top 1 Contributor
Over 11 months ago
MotoSportExpert
Power difference will be minimal between the Powercore and RCT4.1 from FMF. The 4.1 series is the newest line of products for FMF and will have slightly different/more power. Keep in mind you may need to reprogram the ECU on your 2013 Honda CRF250R to see the most benefits from the exhaust change.

What's the difference between the fmf power core and the fmf q4? And do they both have Allen screws or something besides rivets for repacking?
Expert MotoSport Staff

MotoSportExpert
The Q4 would be quieter, both mufflers use rivets.

If I have a 2011 crf250r do I have to so anything since it's fuel injected?

Yes, in most cases you will need to make adjustments to your fuel management system after installing a aftermarket exhaust system. I would recommend getting an EFI controller as well.

Need the same as picture?
Hi I want to buy this muffler but I want to be sure that this one comes with the two holes to hold them, because many of these mufflers comes with one hole only. Could you please confirm me that? Thank you

The mounting point would depend on the bike the exhaust is for. Normally on KTM motorcycles there would be 2 mounting points on the muffler. (Please note the image only is for reference only and may not be displaying the specific exhaust for your bike).

Do I need to any changes to my carberator?
MotoSport Staff

Yes, on your 2006 CRF450x, you will need to re-jet the carburetor after installing this exhaust. To obtain the correct jetting for your bike, I would contact FMF directly at (310) 631-4363 and they can provide you the jetting with this exhaust installed. The other option would be to purchase a jet kit that has the jets you will need and a jetting guide to help jet the bike based on your elevation and the modifications done to the bike. For your 2006 CRF450x we carry either FMF or JD jet kits.
