Awesome Exhaust

Super easy to install, it took me no more than 20 minutes start to finish. Sounds great as well as looks great. I would recommend this exhaust to anyone looking for a quality exhaust for a decent price.

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.

Good top end gain

these new four strokes have came rather far in the last decade. and this slip on definitely opened up the top end. I am very pleased with the price and the fast shipping. moto sports is on it most the time. the spark arrester helps too since my stock pipe did not have one and u must have one to ride on forrest service land. good buy and worth the money.

Excelant for the money

the money u pay for this exhaust is sooooo worth it. its the exact same thing as the factory 4.1 my buddy has the 4.1 we raced and we have the exact bike i stayed like 10 foot in front of him the whole time also it is SUPER QIUET i have a 2007 KX250F and my stock exhaust was louder BUT if u take the spark arrester out its twice as loud but i cant do that cause of AMA specs and when u pull it out of the box its just reaches them but u can buy the quiet core and it will be EVEN QIUETEROTHER THAN THAT ITS AN SEXY AND VERY DURABLE EXHAUST

Awesome pipe

I installed the powerbomb header along with this slip on on my 2007 kawasaki kx250f. It made a big difference in power. I notice it in every gear! Also made it sound a lot deeper as well.

i bought this a year ago, and the only thing i didnt like about it was its a little louder than i wanted it to be im trying to comply with the rules of ama and it exceeds the sound barrier by a lil although i noticed some power gains but other than that its affordable and thats what matter to most of us

Great exhaust. Gave a significant horsepower gain for not very much money, and it's titanium! Fits great, smooths out the power and quiets the bike. Perfect slip-on exhaust.

Q: What's the difference between this and the powercore4?
4 months 12 days ago
Do I need to make changes to the carb? Do you all send a jetting chart?
MotoSportExpert

A: 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.

Q: I have a 2013 CRF250R. What is the difference in power with the powercore vs the rct 4.1?

A: 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.

A: 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.

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

A: 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).
