Loudest and most powerful exhaust

[Honda400EXryd3r]

"i know has been many threds about this but i dont feel like looking threw them"

I have a 01' 400EX and i love the sound of an exhaust that sounds like it's gonna kick your *** not one that sounds like a little 2 stroke... so what pipe do you guys think i should get?

[EXevan91]

i have a white brothers R4 slip on and its plenty loud i love the sound the neghbors and the cops dont tho...

[ZeroLogic]

I have a Curtis Sparks pipe and its loud and has a nice power gain.

actually if u go on DandD racings website theres a pipe for a 400 and they claim with a sproket change it can go 80mph just a pipe and sprocket can u belive that.

Yes, I can believe that you could get 80mph without the pipe too... Just a sproket change you could get going crazy speeds, it'd just be slow on the acceleration...

HMFfor a pretty loud not many out there can beat it throaty sound.... LrD more of a pop noise to it pretty loud also.

[ride_red666]

the yoshimura is one of the best but not the loudest

[Honda#4]

heres the loudest of them all.

[ST87]

[quader400]

lrd for sure.... sounds freaking awesome and really good power gains

[m1ke]

wow loud exhaust you must be feeling like a real bad *** rebeling against the noise pollution law. .

[400exrules]

[400expooner]

it is a pice of crap but im just saying that it is by far the loudest exhaust ive ever heard... that is why i dont have it on anny more

[rooster300ex]

I agree a cobra isn't much of a gain over stock, but damn it runs good and its loud so i'll stick with it till it just won't cut it anymore.

i would go with the HMF or a Curtis Sparks for the loudest. HMF is cheaper i believe.

[scramblerracer]

If you just want stupid loud then cut the back half off of your stock silencer. This will be stupid loud.

[ZeroLogic]

But that won't give you any power gain.

[rooster300ex]

I know having straight pipe isn't a power gain, but if you think about it its letting the engine breath with no restriction.

[exrider008]

i found that my cobra gave me a VERY big power gain but ist just to damn loud.

[nakomis0]

Loud exhausts? Why would you want loud exhausts? lol....

Almost any idiot could build a loud exhaust with some performance improvement... like cobra....

it take skills and research to build an exhaust that has a good power gain and still as quiet as possible,

loud exhaust are annoying.. if its rediculasly fast.. loud is acceptable..

But if your loud as h@ll and still fairly slow.. like 98% of the 400ex out there your just gonna get laughed at.

LMAO:D :D :D

a cobra is a nice gain over stock as long as you rejet accordingly.most people that talk about cobra not making power and blahh blah have no idea what they are doing or they "heard it" from their buddy.how can a more free flowing exhaust cost power over stock?:confused: heres some advise,believe what you "see" and not what you hear.:)

[Honda#4]

i would bet any of u that the DandD pipe is the loudest its a dual straight pipe how can that not be loud.

how is it all in my head it is a relly big power gain compared to stock if u jet it right witch i did so dont go telling me that its all in my head. and do u have a cobra i know they r cheep and WAY to loud but they r alot better then stock.

[mayberry400ex]

if its noise your wantin just take your baffel out its alright i mean no big deal or anything.

if its power and noise your wantin throw a fat boy 4 on there
cant go wrong with that but ther not cheap at all.

best bet is to just get a 17" fmf factory 4

I have a TC race pipe, and it gives great power gains, and there has still yet to been a louder exhaust at teh track, dirtbikes and quads. And theres quads with sparks pipes HMF them all. Although Sparks are close in loudness...but not quite as loud.
CHAD

[ohsobad_chevy]

I got a full system from HMF, I have to say that i am impressed with the gain and the noise level.

[gonenbroke]

well if u want loud then id go with dg r cobra i rele like my dg but it dont got that much of a gain...but then agin i got my ex set up for bottom end cause all the tracks around here are tight and so are the woods
