Power bomb

Great performance and easy to install. I used the GYTR power core muffler slip-on muffler. sounds mean. Great power add on. Only wish it stayed silver after start up.

This header works and fits great with a Powercore 4 Muffler. I recently installed it on my 2009 wr250f and it is so awesome. It really opens the bike up alot.

Great Mid-Top End Power!

The FMF Powerbomb MX header really woke up my YZ250F. The top end pulls very hard! I was skeptical if this mod would produce $170 worth of results. Out if the box the piece looks great and installation is very simple. When first used, the header turns a blueish purple, it's actually pretty neat looking. I could tell after the first fifteen minutes on the bike that I had made the right choice.

Only Con: Does not come with a heat shield, burns pants easily and quickly!

Great fit

I bought this with the FMF 4.1 exhaust. It is light weight, durable and was easy to install. There is no heat guard on this so make sure to wear long pants or riding pants to keep your leg from getting burned.

Noticable power increase

was very pleased with the product. key word "was". after a year of use the header broke in half. dont think they are supposed to do that. wouldnt mind if they sent me a new one free of charge.

Pretty sweet

once hot the header turns a golden brown which personally i think looks good. the power increase i could feel mid to top end. it feels like it will rev faster on the top. if anything it quieted it down from stock. installed on a 06 yz250f

Q: I have an 08 YFZ450 with a 4.1 Power Core. with this powerbomb header will i have to jet my carb ?

A: 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 taking your bike to a local motorcycle dealership’s service department to have your bike properly jetted.

A: FMF doesn't offer a heat shield for the powerbomb. Burning your boot is pretty common though for any head pipe that doesn't have a heat shield. You can use exhaust tape to help out, but it doesn't really look that great.

Q: Does this pipe require a mid pipe, does it bolt up to the muffler, which I have a FMF Powercore 4

A: This will mount up to the powercore 4 slipon exhaust. The mid pipe that came with the slipon will be all you need.

Q: Will pre-engine changes be needed once I go from a stock header to a powerbomb header?

A: If you are mounting this on a stock exhaust their will be no guarantee of correct fitment. FMF will only guarantee fitment only on their exhaust systems.

And to answer your question there's nothing you'll need to do to the engine before installation. Please take serious note to my first comment about fitting this head pipe to anything other than FMF exhaust systems.

what is the difference between the motocross version of this header and the supercross version?
JesseC

A: The SX version gives you a little more low to mid power and the MX version is better for mid to top end power.

Q: Will it fit the fmf powercore IV exhaust?
Over 9 years ago

Expert MotoSport Staff
Over 9 years ago
A: FMF does claim their exhaust components are compatible with most of their line. If your Powercore IV is a slip-on and worked with your stock header, than i don't see any reason the FMF powerbomb wouldn't mount up. They did engineer it around the stock header for fitment.

Q: How much more power will it give you if you have a FMF Q4?

Over 10 years ago
A: You won't really notice much power gain as performance gain. FMF designed the powerbomb header to add more volume to the exhaust system without actually making it longer. That will give the bike more grunt or better low end response. the performance will be gradual through the mid range.
