Honda TRX400ex HMF exhaust sound test

thumbs up for sound and video quality! I didn't re-jet it, it doesn't need it. yes it would make the quad perform better, but it isn't a must. i love the sound! and would definitely recommend it if your looking for something loud.

I bet your neighbors love you

[@atvriders1000]

snound so good you should do a longer running vid i loved this one!!!

[@mgyarnick]

Im so happy I put one on mine it sounds amazing

[@nicholasnarbeth7855]

Thanks for the video it helped alot. Definitely going to by the pipe

[@quaddingsous]

Sounds great!

[@forwarddrive4066]

Sounds clean & mean. Thanks for posting 👍 My 400ex is an 07 but yours is way nicer. Love the rear plastics by the way.👍✌

[@jiapaguilar2495]

That thing fly! Nice machine

[@TheTonganoxiechief]

best pipe ever for the 400ex, got mine last night and sounds so good without the quiet core and the spark arrestor, i have only rode it for litalery 2 minutes around the yard in first and second gear and i have to say in second gear give it half throttle and it will come off the ground into a wheelie! no joke, i was tired of popping the clutch in second gear all the time to get it off the ground since i only weigh 150, best looking to if you get it custom made to match your quad

[@losisupertruck04]

Sounds beastly!

[@tommyteske4536]

We're did you buy it because my friend has 250 ex and he has the Crappy stock exhaust and I didn't know what sounds good on a four stroke

[@jeremy250f5]

Raspy, I love it!

[@Iowawalrus]

King of the trailer hood

[@Borgey401]

Oh and just by the sound of your motor when you slow down or downshift I can tell you are indeed running lean. It's popping when doing so, which = LEAN

[@PrimeRepair]

Kids gonna melt his piston just to save a little time and money

[@Kartmofo]

It seems to have good throttle response, I would bump up to a Keihin 152.5 or 155, it's running lean. You can tell by the popping in decel, I know because mine did the same thing till I rejetted to the above jet size on the main. The 38 pilot is still fine, other then that, great pipe and great video!

[@hOlMeS7871]

I have the 2012 trx400x and I bought the same exhaust but black and I re jet my quad and they are loud and It gives you so more power but you can Go with out it and nice track!

[@noahwelsh8846]

Damn that's a nice ass 400ex

[@aqualungs77]

I love the sound of the 400EX with the HMF! HMF is a great sounding pipe. I went with the full exhaust. Deep breather and loud. I had to rejet to 40 pilot and 180 main. Nice quad man!

[@nathanhayne3685]

Aqualungs what’s your elevation because I just bought a full hmf system and my elevation is 884 ft

[@aqualungs77]

@@nathanhayne3685 it was jetted in Lockport NY, a little over 600' elevation

[@nathanhayne3685]

Aqualungs When you say a deep breather what do you exactly mean is that the type of air filter you’re running?

[@hondatrx400exguy7]

Dude hmf 😈 there good sounding

[@scrumptious54]

@redraidersman96 yeah its a 2008 honda trx 400ex. it rides great, the HMF is the best slip-on to get hands down! this video sounds good, but doesn't do the pipe justice... It sounds great if your looking for something loud with a lot of power and torque. Glad you liked liked the video.

[@redraidersman96]

very nice my cuz has a 250 but he is 10 im 15 the 250 good and goes fast but i want the 400 you sound about the same age. but the 400 you have is a 2012 or 2011 right. im not copying you but this is an exact example on what i want to do. hmf sounds great. finnally able to find a video that is almost a clone on what i had in my head. love the video and great quality thanks man!

[@redraidersman96]

@scrumptious54 yes loved the video it was great, im also looking at kawasaki 450 but idk what i want yet. i rode the 250 but my cuz that owns it is 10. i enjoyed it but still want to check out the 400. but i enjoyed the video thanks!

[@mudman678]

theyre the same thing the trx is always there some people just dont put it. but if you want reverse get an 05 or newer

[@TheTonganoxiechief]

i will be rejetting it soon wtih my dad so i can finally get out and actually ride it

[@mudman678]

just ordered the same pipe for my 04! cant wait. anyone want to see a before and after ill have one up in a week or two!

[@forwarddrive4066]

mudman678 For sure would love to see the install & other mods you have done in a video. I have a 2007 400ex and I have alot of stuff to do to bring it back to 100%.

[@truitons]

ride in a sand pit ! awesome sound ! i got a a Sparks , its louder , even to loud ! nice vid

[@cameronnalley3197]

Anar Chy is it actually louder?

[@codydavie3023]

Where u get the exhaust?? I love the sound

[@nickdavis476]

I have the same Atv and the same pipe i haven't put the pipe on yet but do you have to rejet the engine

[@brandonfox7812]

If it is jetted wrong and you are running to lean it is hard on the motor eventually ruining the top end not fine

[@Borgey401]

Anyone who knows the SLIGHTEST about these bikes knows that they come jetted LEAN FROM THE FACTORY. This mainly to comply with California laws. So in reality you could up the jets on a COMPLETELY stock bike. So when you throw an aftermarket exhaust on which equals MORE AIR FLOW with still that same small amount of gas then yes that means you're running pretty damn lean. Bottom line if you care about the health of your bike then you will rejet it. It's so easy and takes 15 minutes.

[@tvannatter13]

I have a 2008 TRX 400 EX Honda

[@citabria4804]

Imagine a White Brothers exhaust on there!

[@benmusserjr7976]

is that a strait pipe? because im looking into buying one off motosport (.com) for my 2007 honda trx400ex

[@travisengland1368]

Did you rejet your carb?

[@blackman20201]

nise

[@jeb721]

Thats what I was wondering.... Hes just hatin. Its not gonna fry your top end. it may be a little hard on gas but its fine.

[@JacobWinnett99]

I have a 2008 Honda trx 400ex with a 450 carb and new sprockets but I have this exhaust and I can beat my dads raptor 660!

[@cameronnalley3197]

Jake Winnett what do you have to do to have the 450r carb? Do you still have to jet it for a pipe?

[@dukemann20]

have you added anything besides the pipe

[@matthewhoffmann4825]

is this exhaust better then white brothers exhaust?

[@justinsbiever101]

Is there a difference with between the trx 400ex and just a 400ex? Plz help idk what to get but i want speed and a good trail riding 400...thx and i dont want a power loss...possibly with reverse

[@cameronnalley3197]

manneredalloy it's the same thing. Just easier to say 400ex

[@forwarddrive4066]

manneredalloy With Honda you can't go wrong no matter where you want to ride it. Honda will always be Honda. Cars, SUV's, Dirt bikes, Quads, etc... they're just all around great machines. Even the push mowers with Honda engines Outlast any other mower. Hahahaha👍👍✌

[@roedolfrobertson7140]

My bombardier 650 has the same exhaust

[@jakobfeicht8702]

is that a stock heater?

[@zachruberg3217]

Should get an alba

[@EnNergyTrix]

What colors did you get for it?

[@scrumptious54]

@quadracer1243 thanks, and and can you tell its running lean by watching this video?

[@PrimeRepair]

Rejecting doesnt just make it perform better, it keeps you from leaning out the quad and melting your piston.

[@tvannatter13]

BTW i was trying to find a good sounding muffler. If someone could help me i would be happy

[@kadelindenfelser4315]

you dont bring in more oxygen when you put a pipe on it doesnt matter if it was a straight pipe its only gonna bring in and let out so much air and exhaust fumes

[@jared3195]

How much did u pay for it?

[@borgey420]

LOL Classic line in this video is "I didn't re-jet it doesn't need it"...... Someone needs to school you young'n

[@hdsnpoole]

It might sound good, but over time the HMF will misalign your valves because it does not create enough back pressure. Rejetting your carburetor will fix this problem. Also, are you aware that this is actually a 400x and not a 400ex?

[@cameronnalley3197]

Hudson Poole same thing just newer

[@kyleprocon9809]

Did you need to jet it afterwords

[@JSterlingMiller]

I didn’t end up doing it, but it would of course make it run better.

[@kyleprocon9809]

@@JSterlingMiller gotcha

[@lwracing8861]

How much did it cost?

[@JSterlingMiller]

Iceracer1 got it on EBay for $250

Ok cause today when I was racing my friends dad that owns a dealership might sell a dg exhaust to me
