Looks great, sounds great

After installing and retuning, there is a noticable increase in power.

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.

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.

Q: What's the difference between this and the powercore4?
Over 3 years ago
Do I need to make changes to the carb? Do you all send a jetting chart?

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.

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.
