Sound Comparison FMF Q4 vs. FMF Powercore 4

[@xxZR2xx]

its not a good comparison, 2 completely different motors, there for the motor does not create the same sound out of the exhaust

[@AU_aup]

1:31 power core Sound 2:40 Q4 sound Thanks me later😊

[@neolightproductions]

I'd love to see this on two identical bikes. Also with the stock exhaust to get a control. How much louder is either than the stock exhaust? How much gain in power too. Wish I could see those comparisons.

[@alexwilson2961]

I also have a ttr 230 2011 and I was wondering which one would be better and this video helped so thank you

[@RedKnightHobbiesyoutubepage]

i agree, you should use the same motor and switch mufflers

[@76SRV190]

The correct way to do a DB reading is hold the meter 1M away from and within 10 degrees of the center of the outlet and rev motor to 1500rpm.

[@stevenbegonia3560]

how do you do a comparison between 2 different bikes for exhaust. derp

[@mitchellyinger9051]

The powercore is going to have a bigger power increase, but the Q4 will be quieter. I'm not sure but I think that the powercore will probably be lighter.

[@2phalanges]

theres alot of misunderstanding why riders get this. I get it cuss on the freeway they cant see me, with this pipe at least they can hear me and be more aware of their surroundings. this shit save my butt.

[@XrhstosGr]

that's very very true mate

[@elguitarTom]

Let's be honest; you got it because it sounds cooler. Loud pipes don't save lives. Safe and smart driving do.

[@MofosRealReviews]

How ironic that shit saved your butt am I right?

[@jingelsby]

Hey man..GREAT VIDEO! now, Witch Muffler do you like better the Powercore or the Q4?

[@ファレノプシス三世]

2:04 POWERCORE4 3:13 Q4

[@c0uchsl0uch]

will either muffler cause the blinker to melt on the klx250s ?

[@CheerX9087]

Love the sound of the Powercore. Sounds like a chopper.

[@KiTSaRaS86]

do they have any deference in the performance and the weight for a klx 250 or they are the same? except the sound :p

[@claddagh1000]

which bike did or do you like better?

[@ktmdays]

Im.getting.a fmf 4.1 what's the difference between the q4 and the other one

[@devindelight9492]

So the powercore 4 the one to get if you wanna get people to look

[@BangJoMotoVlog]

I like the sound

[@Ar4Moroz]

Hello! What about fuel consumption?

[@spensports]

which has more power?

[@bh7480]

I think fmf have the best sound am looking to get one for my klr 650.

[@dan3428]

So basically what yer sayin is get the powercore 4

[@TheMarco1492]

Well both are 250 so its essentially the same if you remove the stock pipe cuz its the stock pipe of each branch that make the sound different really

[@ktmcapone7388]

hey did u need to re-jet ur bike after getting those pipes

[@trooptropical]

No

[@T3merity]

Any time you change the flow of air in or out you need to rejet your motorcycle.

[@RandallMckinney1]

need to get one for my bike

[@jamesbonde9488]

Did you have to do any jetting when you put the Q4 on the KLX?

[@kotchman124]

I have one myself, you need to rejet it otherwise it will run too lean.

[@larswgjethammer6831]

Hey, i want to quiet down my yz 85 2015. I want to change the stock silencer to a FMF Q. I do not want to lose power. Can i use the FMF Q with the OEM pipe? Or do i need a fmf fatty too? And do i need to re jet? I dont know what re jetting is or how to do it..

[@haydenfrench7878]

there are jets in the carb, these are small holes that the fuel runs through, when u get a higher flowing exhaust then you will need to get more fuel into the engine therefore you get a bigger bang and more power, if you dont do this then your bike can run lean and go worse and get very hot

[@bongodave13]

Go to Thumpertalk or a forum for your specific bike and ask there. You usually have to re-jet, but it's not hard. Other people have done it and they can walk you through it.

[@Kiwi-tz8vm]

Is that a slip on power core 4

[@seamuskillilea]

Did you rejet?

[@MichaelSmith-ke9wk]

will I defiantly have to rejet if I buy a powercore 4? if so, what size?

[@gokuggsupersaiyan3023]

Michael Smith no

[@keithslade9379]

yes "defiantly"

[@michaelosullivan8288]

Lexx mxe is way louder then any brand of mufflers and if you put lexx mxe,two brothers,hmf,FMF,all in line to start up then you work out which is has more sound in their bike

Buy a JD jet kit and do it yourself. Welcome to owning a bike with a carburetor. Might as well learn sooner than later.

[@TheWelder93]

yes you need to get the carb jetted if you put an aftermarket exhaust on, if you dont jet the carb with an aftermarket exhaust your bike will run too lean

I heard its a good idea to take off stickers due to heat. Is that true?

no the stickers are heat resistant

You don't have to. They'll last. I take mine off, anyway because I don't want the stickers.

[@kylestevenson6213]

None of that has to do with how loud the muffler is. You obviously don’t know how the decibel system works and how truly loud your claimed numbers would be

[@ardennielsen3761]

@@kylestevenson6213 a muffler doesn't make noise. advanced exhaust valve timing makes everything horribly loud.

[@kylestevenson6213]

Obviously a muffler doesn’t make sound, you could even say it “muffles” sound. And advancing or retarding the exhaust valve timing won’t have a dramatic effect on overall exhaust volume. If anything modern engines are quieter than anything that came before. You’ll never have me believe that a motorcycle at “light revs” is as loud as a jet engine at full power. Even with no muffler whatsoever you’d never even get close to that level of sound.

[@FullTimeRCer]

every 3db is twice as loud

[@IISHEEVAII]

powercore 4 wins

[@rangerdanger222]

The decibel scale is logarithmic. a 10 decibel difference is 100 times louder.
