Out of those two, I am going to state that I was not impressed with the WB. The one on my buddies z400 did nothing but increase the noise level.

[397ccEX]

well what about the T-4 thats kinda what Im leanin towards

[bpimpdaddy21]

I have the T-4 on my EX, and it made a big difference. I was able to pull a gear higher in places that I was searching for the gear before the pipe. Make sure you put an air filter on at the same time also. The T-4 is awesome!

[TRXRacer1]

I agree with bpimpdaddy21, the T-4 is a real nice silencer that adds power and a nice sound.

[foleyit]

I had the white bros. e-series slip-on pipe on my quad for 2 years and it was fine. The white bros. e-series was one of the best performers in the Dirt Wheels pipe shootout for the 400ex. One of the benefits about the WB e-series is that it has a disc system which allows you to add/remove discs which affects the way you want your quad to perform. Granted there are some new pipes out on the market that didn't exist back then.

i had a t-4 slip on on a 250ex it picked it up a good bit but that was in 2002 and it was a slip so you will git a lot more out of it now and if it was a full so i say go for it:)

Holy crap, I would pay big bucks for a pipe that added 6-7 HP alone!

I'd go with the T-4 even when people make false claims like that about it :p .

[2001300exguy]

hmf usually goes for around 200if your a member of their forum you get 20 off and you can get jets from the for 5

[397ccEX]

Is the t4 really loud?
Did you get a noticable amount of power from it?

No it's not that loud, it has a nice sound to it. I can def feel a differnce when I switch back to my stock. The t4 really helps it out all the way from low to top.

[skippy]

i had a white bros e on my 416 but then i switched to a gt thunder wow what a difference

[397ccEX]

will it give it a noticable amount of torque?
thats what I want and maybe a bit more top speed
Who knows which one gives you the most power?

[cletusEX]

I ran a T-4 on my 400 for 2 years. I like the pipe. It made a noticable difference over stock. I now run a HMF and like it a lot more. It has a better sound and overall power increase is better IMO. If I had it to do over again I would have bought an HMF in the first place.

[397ccEX]

hmf gives more power than a t-4?
is it louder?

[TRXRacer1]

You won't see any power difference between an HMF and a T-4 silencer because the HMF is basicaly just a copy. I couldn't tell you about the full systems.

[jahaiap]

is the hmf really a copy... i mean besides looks what makes you say that?

Make sure you know what your talking about before you open your mouth. I infact have a full t-4 system, had a yoshi slip on, and now have an HMF slip on. I had the yoshi slip on on my 416ex but i sold it because the sound sucked and didn't feel any power gains really. Therefore when i sold it, i had a race coming up that weekend but the HMF was ordered and just came this week. I mounted the t-4 system up and took it for a ride. The t-4 header seems just like a longer stocker, the t-4 silencer is smaller than a yoshi and does not flow at all. On the other hand, i just received the HMF slip on Tuesday, mounted the stock header, and the HMF canister. The HMF canister is huge compared to the T4 one. there are in my way a copy of a T4. The HMF is nicer quality, sounds alot better and flows so much better with a big opening. I'd say get a HMF slip on. Any more questions, just ask.

[CTmxyfz]

Small T4 can

[CTmxyfz]

the T4 was from this weekends 11/7/04 race. Now the 416 sports this.

Note, the endcap was on the wrong way but fixed now.

[cals400ex]

the T4 header should fit all slip on silencers. the HMF uses a different silencer for their slip on and full systems. my buddy bolted on a full HMF the other day and it ran so much better than the R4 slip on he had. i honestly wouldn't be cheap and just by a complete system now. i ran an x-6 on a stock bike and it was fine. i realize some of the slip ons are made for torque. if you just do woods riding, a slip on should be fine. however, i do a lot of dragging and you can tell a pretty big difference between slip ons and full systems, especially when you do a few motor mods.

http://www.bluetraxx.com/phpBB/images/smiles/bs.gifFirst of all just because you change a design a little and make it bigger, it doesn't mean it's not a copy, it is. HMF makes an okay product but they are not better quality then a PC. Also, unless your running a big bore and stroked motor the T-4 silencer is more then big enough. It's the oldest misconseption in the book, bigger is NOT always better.

[keljas21]

Is the HMF Slip on Good?
how loud is it

[CTmxyfz]

HMF slip on is worth it. Get it, you will be happy.

TC shorty gets my vote;) :cool:

[2001-400ex'er]

My brother and I both have them on our 400s and could not be happier with the HMFs. Great quality, great price, great power gains, great sound. http://www.imagestation.com/picture/sraid146/p690a3a7c81ead1da79d2cd18cbcae543/f647718f.jpg http://www.imagestation.com/picture/sraid146/pa9575aca995592c8fb6f7042ed3105d9/f653bd0b.jpg

[397ccEX]

How loud are those HMFS
I still havent decided procircuit t4 or HMF
ANY downfalls TO THE hmf or t4

[panteramatt]

For one, a t4 will NOT give you 7hp hate to tell ya. Maybe 3 rwhp if the engine is stock. The wb is a good pipe I have one on my z and like it cause its not too loud for trail riding and stillgave me a decent hp boost. Sparks is the best pipe for the 400ex hands down for hp but its expensive and tool loud if you have anyone nearby. I personally like the hmf for price, hp, and looks. You wont be dissapointed ni any of them.Just make sure you take the box lid off, put a better airfilter on, and jet it and youll see maybe 6-7 then if your lucky.

[397ccEX]

What about full T4 OR FULL HMF AND KN FILTER
HOW MANY HP?

[panteramatt]

With either pipe on and jetted right with the airbox off and a good airfilter I woud say around 5rwhp but thats to the rear wheels which is how everyone should measure it. I would say around 8-9 to the flywheel.

if you are really down to one of those two brands, get the full HMF. don't skimp out and get the slip on. the full system does make a difference.

[JDiablo]

man who ever argued that the PC is better then the HMF keep your mouth shut,only thing the pro circuit is good for is two strokes,if you want the power you need get a HMF full system,the DB levels of the full system without quiet core is from 103-105,with the quiet core is 96-98 dbs
with K&N filter and properly jetted you should at the highest reach 4-5 hp if your lucky
but mostly you'll have all the power you need from the HMF,my other selections on pipes would be sparks,lrd,tc,gt thunder,etc

[kssandduner]

Wow!! Three pages on exhaust and not a single mention of Curtis Sparks???:huh Anyways....when I had my 400ex I had a LRD full system, and my dad ran a Sparks full system on his ex. The LRD made more power down low than the Sparks, I could ride wheelies way easier than he could, but in the mid to top end the sparks pipe really shines. While drag racing we were always dead even till about fourth gear when he would slowly pull away from me. If we were drag racing from a dead stop at the bottom of a hill on the dunes, it was a different story, my torquier LRD would smoke him. Both pipes are awesome imo, just something else to consider!

uhh i just mentioned it:huh

[kssandduner]

Oops...my bad. That wasn't really the point anyways bananna lover or whatever you call yourself. It's just rare in these forums to go three pages on an exhaust subject till you hear Curtis Sparks mentioned. And I ain't got nothing against Sparks either, their stuff is awesome.

Joe

[panteramatt]

UMMM I think I said that sparks is the best pipe hands down.:rolleyes:
