big gun or yoshimura for 400ex?

[much2fear]

Which pipe is better for hill climbing for a 400ex? These are both full systems.

thanks

Big guns are not as good as a Yosh. If your doing hill climbs I wouldn't get a full system. You'll have better grunt with a slip-on and your stock head pipe.

yea get a yoshi slip on

[400exstud]

yoshi

[Kennethyfz450]

1.fmf powerbomb header

4.sparks

5.ct racing

6.trinity

7.yosh

8.fmf powercore

9.big gun

10.dg

11.cobra

The stock headpipe would be better because it gives more low end power than a bigger diameter pipe.

I would think a Big Gun would be an excellent choice for hill climbing because of the low end power it gives. I have a Big Gun slip-on and before when I had a 14t on it would pull like a 440.

wtf? y does everyone talk so bad about big guns?

[littleugly03]

because they suck you should get the R4 or the Hmf those are the 2 best pipes for the 400ex.

how would you know, by reading reviews in dirt wheels?

[littleugly03]

no because i ride with all the guys a hatfield and jeff and they would say the same thing and my brother ugly would to

[400exstud]

anybody wanna say that there are "the best" pipes for different types of riding. x-6, and white for top end. t-4 and yoshi for mid. big gun for low end.

that's just how i see it. any pipe can be a shinning star in the type of riding it was ment for.

[ny300exrider]

big gun is a good hill climb pipe its got good low end which will help you lug it up the hills

Why do they suck? just because you say so?

[FasstMidnightZ]

i'm with chucked all the way big gun is a great pipe for low end . how come u dont think so :ermm:

[Toadz400]

Well, at least I know of two other people on this site that support Big Gun...

What is everyone's problem with Big Gun? I can promise you it makes a lot more bottom end than an X-6 pipe or a Yoshi pipe. And the last time I checked, you don't want a top end pipe for hill climbs?

Go with Big Gun and a smaller front sprocket!

And whoever said R4, what are you thinking?? I'd take a Cobra pipe over one of those anyday! Pieces of crap and they fall apart!

and you can polish it and make it look bling

Is it true that I would lose some hp with a big gun?

NO!

Why does everyone think the Big Gun is horrible??? If you want something that sucks, get a DG or Cobra pipe!

sorry, that was just something i heard on other forums.

does the big gun have a nice sound to it? how loud is it? Oh and im talking about the race series

[YZ400EX]

I used to have a big gun full system and I loved it! Couldnt say anything bad about it ever..The system that I had was super loud, but sounded great..It definately gives a tremendous amount of low end power..I switched to HMF just because I wanted to try something else, but the Big Gun was great..Dont let anyone tell you different!!

[initall]

I love my Big Gun Race slip on it is loud, I get compliments on it all the time on how it sounds. And the low end power is great. I wouldn't trade it for any other pipe.

[Toadz400]

The Big Gun has an awesome deep throaty sound to it. I'd definately get it if you're looking for good low end gains.

[much2fear]

will there be any top end increases, or will it be like stock on the top end?

I want to also add that I will be running it with the airbox lid removed, a K&N air filter, and of-course the proper jetting.


Thanks

i have a 440 with the big gun full race system and it rocks,no problems with it here, get a big gun system and you wont regret it.

There will be little top end gain, the pipe focuses highly on low end and mid power. I run mine without an airbox lid and it helps greatly with throttle response. You will definately notice when you have the jetting dead on - you won't be able to keep the wheels down.

[Vince44]

I would go with a Big Gun Race series

I have one on my 2005 400ex and it pull very hard compared to the stock
a lot better than the yosh.
It have one of the best sound i've ever heard,
very loud:D

Get a Big Gun and you wont regret it

[FasstMidnightZ]

couldn't say it better my self :)

For low end power Sparks wouldn't work, at least the X-6...I have never tried the X-4 though, but I doubt it's as good as a Big Gun for low end power.

[QuadJunkies]

Ive had three Yoshis and LUV it on my Honda!!!... I think that would be a great choice from the two........ ;)

[jhr400EX]

I love my big gun. Great low and mid power, and sounds really good too.

Thats like asking, peanut butter and jelly or ham and cheese? and saying "turkey and mustard"

[cals400ex]

my buddy switched from a big gun slip on to a x-4 and he gained about 3 bike lengths in a drag race from 1st to the middle of 5th gear, which is quite substantial. this was on a mild 406.

[jahaiap]

my friend has a big gun race full and he sapnks me like a redheaded stepchild off the line and through midrange...but on top end he cant walk away from me...besides his jetting that is the only difference in our 400s

on a built bike any system would gain that much.:scary:

[Steve-o 400EX]

I swear by my e-series, i have a 416, hotcams stage 2, stock header, i run it with no discs and it screams up hillclimbs, it will bounce off rev limiter all day.:macho

i wouldn't put money on that :macho


also, i really wouldn't consider his bike built. he had a rated 10:1 wiseco piston. which the compression was probably closer to stock than 10:1. it was 1mm larger than stock, which isn't much either. he was running a stage 1 cam. going from a slip on to a full system and gaining 3 bike lengths is quite a bit. he had he welds in his stock header grinded off too. losing by 3 bike lengths in a drag is getting beat pretty bad.
