Arrived on time and fits the pit bike

The product was delivered on the expected date. it is light and easy to install on the Honda 50cc. If you need a muffler replacement at a reasonable price i would recommend this one for you.

Quick and easy bolt-on performance upgrade. Looks and sounds amazing! The XR 100 sounds like a "big boy bike" now.

Not a Stainless Steel Header

This is a real good system at a really great price. We purchased this for a TRX 250X and were pleased with the results. The head pipe is chromed steel and NOT STAINLESS, just so you know. The description is a little mis-leading so read ALL descriptions carefully for your specific application. The silencer sticks out past the grab bar on the 250x about 2 1/2 inches so keep that in mind, you may want an extended grab bar. Other than those minor things, we love the pipe and would recommend it.
It really opened the 250x up throughout the whole RPM range.

FMF complete exhaust sysytem is perfect

The exhaust system mounted with no problems and is sturdy. Sounds great. Have the same exhaust on my 400ex & son's 300ex. Buy the FMF power up kit and call FMF to help you get the right jet and your e-clip in the right place for adjustments.

Great exhaust

I have a honda 300 trx. I installed this pipe on it and was impressed with the ease of installation,and it sounds great.It does stick out a little further than my old one but i just extened my grab bar 3 in to protect it. I jetted the bike and the combo really woke it up. Im verry pleased with the performance.cant beat the price.

TTR 90 Upgrade

This pipe added more power and torque to my 90 and it sounds better. the only problem installing was that i snapped one of the bolts so it took me 2 days to install

BRAAAAAAAAAAAAAAAAAAAAAAPPPPPPPPPPPPPPP

I installed the PowerCore4 on my friends 03' TT-R90 and it defiantly increased the over rev and torque of the motor! It sounds amazing over the stock pipe. I for sure recommend this pipe for any 4 stroke! You can definitely tell a power enhance on the smaller bikes.

WAAAAA!

This almost doubled the power on my crf100f. Rejeting it after installation was a pain. When i was installing it the nuts that where on my bike they got striped but that was my own fault. MAKE sure you rejet it or you will blow your motor. overall really good product.

Best purchase

This pipe is the best. I installed it on my 2003 TT-R 125 and it makes that thing move. You will gain alot of power, more speed and a greater sound almost like a 450f.

Awesome Exhaust.

I got it for my 2007 Yamaha TTR-125L and it made a huge differance. I got more power from low to mid, its much louder and sounds great, and im also really glad that i bought it when i did -i little over 2 months ago- because it was a lot cheaper, i only paided $145, when now the cheapest on here is $161-$179, for the 07' TTR-125. but still i would recommend this to any of my friends. It is definitely the first thing i would recommend doing to any TTR-125.

Q: Will this fit my 2005 crf70 with a lifan 140cc motor?

A: Fitment with a Lifan 140cc motor can not be guaranteed. You would likly not have any issues bolting on your 2005 Honda CRF70, however I would recommend checking with the motor manufacture to see if they recommend a certain pipe that works best with their engine combo. I tried many exhaust combos on my Honda CRF70's and CRF50's with different engine set ups and found varying results. I found that the high flo Two Brothers exhaust seemed to work best for me on my big bore set ups.

A: If by decals you mean stickers? normally fmf encloses at least one sticker in each order. But this is totally dependent on fmf inc. If by decals you mean the fmf logo on the exhaust then yes it will.

Q: Do I need to rejet a 2000 XR 100?

A: Some jetting changes may be needed on your XR100. If your bike is currently jetted properly you will likely not have to make any changes after installing this FMF exhaust. 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: Depend on your location (altitude/temperature) and how your bike is running with the current jetting you may need to rejet or make minor adjustments. Jetting can be very tricky, there isn't one setting that will work everywhere with every bike.

A: You should not have to change the jetting on your 2007 Honda CRF100F when installing this FMF Powercore 4 exhaust. FMF recommends stock jetting. 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: Yes you will most likely need to make some setting changes when installing this complete exhaust. There is not a specific setting I could give you for jetting your bike. It would really depend on your location (altitude/temperature) and how your bike is running with the current jetting. Jetting can be very tricky, there isn't one setting that will work everywhere with every bike. I would recommend getting a jet kit and taking your bike to a local motorcycle dealership’s service department to have your bike properly jetted.
