    The FMF Power Bomb Header Pipe is always a solid choice when you want great sound, extra power, and straightforward performance added to your dirt bike or ATV.

    The stainless steel construction of the Power Bomb makes a pretty package. But the center of focus is the "Bomb" module precisely located on the header, giving you up to 10% better exhaust gas flow. The Power Bomb uses its dual chamber design to circulate gas through an external chamber where it expands and contracts before exiting the header at an increased velocity. This increased flow will give you a snappier throttle response and a noticeable bump in performance.

    The external chamber also acts as a type of "pre-muffler" that lowers the exhaust note up to 1.5 decibels for a deeper, throatier sound. The FMF Power Bomb easily bolts on in place of your stock header and is a perfect pair with FMF silencers to create a complete package.

    Specs:
  • Aftermarket header pipe for your motorcycle or ATV
  • Increase in gas flow up to 10%
  • Lowers exhaust note up to 1.5 Dbs.
  • Decreased weight vs. stock
  • Increased performance range
  • Modular exhaust port flange
  • Outer expansion chamber increases gas velocity
  • Increased throttle response
  • Perfect match with FMF silencers
  • NOTE: FMF does not guarantee the Power Bomb's fitment to stock mufflers

Good and light, but likely not what you think with spending the money.
Honestly I think the hype is higher than reality, but thats the case with most basic performance mods. Its a placebo effect with minimal real world gain.

With that said, at least on my DRZ400 I did notice a few minor perks. Firstly, yes its larger diameter than OEM. Better flow, so jet accordingly with a matched muffler. Second, it weighs half of the stock pipe. Thirdly, its stainless so not much to explain the benefits of that in itself.

With that, there wasnt much noticable gain on my DRZ with 3x3 mod and proper jetting and after market filter( I use a Moose which are great btw). It does have a "tiny" bit of top end gain. But with basic physics, the larger diameter and greater flow with that tiny bit of top end, the bottom end grunt was diminished equally tiny amount. Double edged sword with overall flow and back pressure change.

Overall I do like the pipe as it looks way better than stock and weighs allot less. But honestly its all in your head power gain without major motor changes itself when it comes to exhaust. I have a Q4 with it and like the whole system in general. The gain in better tone and weight redu tion are the best benefits with any exhaust system by itself.

On a side not, i actually kinda like how the Q4 sounded with the OEM header over the powerbomb, it was rounder and more mellow. With the powerbomb its actually a little sharper in sound. But it isnt unbearable. Also fit well but was a bear to install with muffler.

This was all on a 2018 DRZ400S with 3x3, Q4, jetting, and air filter change, and is my opinion. Have about 300 miles on the exhaust system so far or a little more.

If you want a fancy looking light replacement, this works well with some tiny gain.

Great sound and better looking than stock
I own a 2015 KX450F. My factory header was all worn out and rusty. I didn't have a huge budget to replace my header pipe. Then I came across the FMF Power Bomb header. You can not beat the value of this very simple up grade to your bike. It will be one of easiest installs that gives you great looks (people think its the Titanium because of the color it turns when hot) and better performance.

The fitment on my bike was perfect. The quality of the hardware is top notch. Love the bend of the pipe and how all the welds are done.

I highly recommend this part to anyone looking to get rid of there old factory header pipe and get more of that factory look. A great value at this price.

Best. Header. Ever.
The FMF powerbomb header is probably my favorite engine upgrade. Paired with a Powercore IV it makes a real nice throaty tone. Keep in mind when you swap the header on a carburated bike you're gonna have to rejet. Getting that done it looks real good mounted on the bike, functions perfectly, and being stainless turns neat colors when hot (mine turned a blueish purple color). Probably the easiest engine mod (save for a sparkplug) to do. Took 5 mins to install. I'd give this more than 5 stars if I could.

FMF Power bomb head pipe.
Put a FMF Q4 in as well and the power bomb really brought it all together. I rode it one day with stock header but jetted it forma full system and that day it snap crackled and popped upon deceleration and sounded like crap. I put the power bomb on and it made all the difference runs great and no crackling anymore and I notice the difference in tourque.

Nice Header, But Doesn't Fit Aftermarket Silencer
I bought this to go with a Lexx Slip-On after discovering that the factory header was too rusted to use. The diameter of this header is larger than the factory, but smaller than the Lexx. The adapter for the Lexx didn't work, and the gap was too large to jut fill with silicone. I took the Powerbomb to an exhaust shop and they were able to expand it from 1-3/4" OD to a little over 1-7/8" to work with the slip on. It must be good material, because it stretched and didn't split.

Quality Upgrade for KLR650
The KLR650 OEM header is heavy, ugly, and outdated. Within 5 miles it begins to discolor and makes the whole bike look worn out. This header really spruces up the bike. Performance gains are marginal, but with a KLR, every little bit helps.

Lexx MXe Slip-On Silencer With Mid-Pipe

BEST ANSWER: Yes, I have this same combination and it works great. Just use some silicone seal on the joint. No clamp required. And replace the Lexx springs with some good-quality exhaust springs like FMF.
just one powerbomb? or does it come for each side? for a 2000 Honda 400ex
A shopper on Sep 28, 2016
BEST ANSWER: The pipe for the 400EX is different than what is pictured. It has two pipes from the head that fuse into one which then connects to the muffler. Essentially the same design as the OEM header pipe but with the Power Bomb technology.

FMF Carbon Heat Shield for Megabomb Header
FMF Carbon Heat Shield for Megabomb Header
BEST ANSWER: It is designed for the mega but a smaller hose clamp may be able to be used to make it work, although it may not look quite right because the chamber on the power bomb is a different shape.
Will I have to rejet my carburetor when installing this pipe?
A shopper on Dec 3, 2016
BEST ANSWER: IT REALLY DEPENDS ON YOUR ALTITUDE AS THAT IS VERY IMPORTANT. I USE THE JD JET KIT FOR MY CRF450X AND AS PER THE MANUAL WITH IT, THEY HIT IT ON THE NAIL AS I AM AT SEALEVEL. I TRIED THE FMF MEGABOMB FIRST AS I HAD ONE ALL READY BUT THE BIKE WOULD FEEL TOO RACEY OUT FROM THE MID POWER. THE POWER BOMB CLEANED THAT UP AND NOW VERY SMOOTH TRANSITION TROUGH THE WHOLE CURVE. IF YOU ARE AT THE MID TO HIGH ALTITUDES YOU WILL MOST LIKELY HAVE TO REJET ANYWAY. THIS IS WHAT WORKED FOR ME. GOOD LUCK AND HAPPY TRAILS!
What hardware does it come with?
Cameron W on Oct 29, 2018
BEST ANSWER: I bought the header and the Q4 silencer at the same time, so I can't remember which one comes with clamp to connect the 2 together. I do know that you will use the factory bolts for connecting the header to the exhaust ports on the front of the engine. i didn't have to come up with any hardware though. If you get the silencer or already have one, the only thing extra i did was put a washer where silencer mounts because it's really close to the wheelie bar to give a little bit more room, just to make sure it would not rub and scratch the silencer, and then I put a lock washer on it for extra protection. If you want a lot better throttle response, I would suggest also getting the K & N Xstream Powerlid. Best $109 dollars I ever spent on a ATV.
will it fit with my lexx exhaust on my 15 KLR?
Matthew G on Feb 15, 2017
BEST ANSWER: Sorry, I don't know, I matched it to the FMF Q4 I bought at the same time. I recall one of the videos of Rocky Mountain's tricked out KLRs had mentioned something about that when they were comparing FMF, Lexx and another slipon, but it's been a while now. HTH, They've got some smart folks on the chat, and by email that might be of more concrete help.
Does this header come with new gaskets for either end, head and/or muffler? I dont want to reuse crush gasket 2001 klr650.
Nathan B on Mar 6, 2017
BEST ANSWER: Yes it does come with new gaskets
What heat shield will fit the powerbomb on 04-05 trx450r?
A shopper on Feb 12, 2017
BEST ANSWER: FMF makes one specifically for the PB. I don't see it on RM anymore, not sure if it's dropped. Moose/e line also makes one, but it doesn't fit the crf right, it sits on top, not so much the side. I've been looking for the perfect shield myself for a while.
To confirm, this will mate properly to the FMF Q4 slip-on exhaust, correct? I realize this may sound redundant but I want to confirm. Cheers!
Frank L on Feb 1, 2017
BEST ANSWER: Slips on with no issues at all. It was a quick swap out of me.
Does this PowerBomb Header pipe come with two headers that fuse into one? Will it fit my raptor 700se 2009
A shopper on Feb 3, 2017
BEST ANSWER: I'd presume it's probably the same design as my '02 660 Raptor. Two head pipes into the power bomb chamber that sits @ 9" in front of the muffler. FMF makes great made in USA products. If there's rejetting to be done, they give you the info of recommended ones they used. They're absolutely great about returns if needed.
Will this head exhaust fit a 2008TRX450r with a yoshimaru slip on?
Jacob F on Feb 7, 2019
BEST ANSWER: If they list your machine, yes. My install was an '09 XR650L. Head pipe and FMF Q4 fit great. Don't forget the exhaust gaskets!
Does the Powerbomb come with the MID PIPE for my 2012 KTM 350 sxf or do I have to order that separate?
Raleigh C on Aug 4, 2018
BEST ANSWER: Dont forget the jets your going to want to play with your air a bit open up the box
Also get a few jets to play with. That's when youll get the goodness from that pipe
For my 2012 KTM 350 sxf - does this header pipe come with the the mid pipe as all one piece same as stock? If it’s 2 pieces - a header and a mid - are they sold separately or will purchasing this item get me both? Thanks.
Raleigh C on Jul 23, 2018
BEST ANSWER: On my 2014 KTM 650 no mid pipe. The header and my FMF Power Muffler bolted up. No mid pipe, was needed! I did pick Low and Mid Range Power/Torqe !! They work !! Also K/M air Filter was used.
Can I use this header pipe with a Yoshimura RS-2 Stainless/Aluminum Slip-On on a KFX450R?
Shaun M on Sep 15, 2017
BEST ANSWER: FMF makes their header pipes to also be able to marry up to your stock silencer. If the Yoshi slip-on is made to also fit on a stock header, then in theory the powerbomb and the Yoshi silencer should connect. The unknown is the exhaust side pipe diameter of the powerbomb and whether or not it is the right size to fit inside the opening of the silencer. FMF also sells aluminum sleeves/adapters that may be needed. My recommendation would be to call Yoshi or FMF customer support to ask the question just to be sure.

The other thing to consider is that the components are all part of the exhaust system. In engineering terms, a system is a combination of components designed, when put together, to produce a particular outcome. These companies design their parts to work best with each other. You may not get the same performance outcome if you blend products from different competitors.
Already have a FMF 4.1 slip on....will it be compatible with it?
Robert M on Jan 19, 2019

Will this work with a HMF slip on ?
Robert S on Jan 8, 2019
BEST ANSWER: I'm not sure if it will work with other slip-ons. I purchased this header pipe and the FMF Powercore IV together and have not been disappointed. Great sound and noticeable throttle response.

I bought a lexx exhaust for my 2005 honda 450r Will this header fit?
Johnny L on Aug 2, 2018

Will this fit a stock 2017 kx250f silencer?
A shopper on Feb 22, 2019
BEST ANSWER: I have it on my Suzuki DR 400 out to the FMF Exhaust silencer. I would assume it defeats the purpose to open up the exhaust from the Cylinder only to restrict it at the silencer. I would highly recommend buying the header and matching silencer from FMF. I also recommend opening up your air intake with a KN filter.
