Did you rejet your carb?

Did you need to jet it afterwords

Imagine a White Brothers exhaust on there!

Dude hmf 😈 there good sounding

King of the trailer hood

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

How much did it cost?

My bombardier 650 has the same exhaust

That thing fly! Nice machine

How much did u pay for it?

Sounds great!

is that a stock heater?

Raspy, I love it!

is this exhaust better then white brothers exhaust?

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

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

I bet your neighbors love you

Sounds beastly!

wow!

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

Im so happy I put one on mine it sounds amazing

Damn that's a nice ass 400ex

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

the trx 400ex is a 400ex

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!

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.

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

Where u get the exhaust?? I love the sound

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

Yuhhhh

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

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

nise

Should get an alba

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

I have a 2008 TRX 400 EX Honda

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!

have you added anything besides the pipe

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?

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

What colors did you get for it?

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

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

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.

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!

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

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

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!

I CAN PROMISE YOU IN MY NEIGHBORHOOD THE NEIGHBORS WOULD HAVE YOU OR I ON VIDEO AND THE POLICE DISPATCHED AS SOON AS THE START UP TO FINE US FOR OUR SURPLUS MONEY AND TAKE GREAT GLEE IN DOING SO.
