GETTING MY TWO BROTHERS IN TODAY, IM STOKED, I HAVENT SEEN ANY DYNOS OR PIPE SHOOTOUTS ON THIS EXHAUST I GUESS BEING BECAUSE ITS FAIRLY NEW. EVERYONE IS RUNNING THE DASA AND I DIDNT WANT TO BE LIKE EVERYONE ELSE, HOPEFULLY THERE WILL BE BIG POWER GAINS WITH IT. FUEL ATV DID THERE PIPE SHOOT OUT AND MOST OF THE EXHAUST THEY RAN WERE VERY VERY CLOSE TO EACH OTHER.

WOW... you got a smoking deal! I wish I would have found that, I paid 225. shipped for slip on only. I cant see getting rid of my titanium head pipe for stainless. Im sure you could get a extra horse or two but im not that serious with it

I dont mind the loud, im riding on my 150 acres only. I would like to see the two brothers dyno'd like fuelatv did in the pipe shootout, I suppose the two brothers wasnt in production at the time.

+1 for two brothers exhaust being loud, I have it on my o6 gixxer750....but for a quad I am kinda staying away from them and trying to afford a dasa :).but two brothers makes a silencer that nocks a few db's off.

IM LOVING THE WAY THIS PIPE SOUNDS, WOW. AND CAN FEEL A DEFINITE INCREASE IN THE BOTTEM END AND IN TOP. THE PIPE IS THE FIRST THING IVE DONE TO THIS THING SO FAR. FUELATV INTAKE AND POWER COMMANDER IS ON THE WAY. TWO BROTHERS SOUNDS WAY BETTER THAN MY HMF ON MY 400EX. IM GLAD I WENT WITH THEM, IT WAS BETWEEN YOSH AND TWO BROTHERS.

2 Brothers makes some awesome pipes. I have one on my TRX450. Like you said, great low end gains but very loud. Due to sound regulations I had to put the quit tip on. Here is what it looks like.

I have a two brothers on my 700xx and love it. I too bought mine used for a great deal. Since I bought it used I asked Two Brothers for some stickers (they sell them for like $8.00) and they mailed them to me for free.

Anyway, can't say enough good things about mine:

Is it just me, or does this head pipe have sleeker bends in it, keeping the thing tighter in than stock?

na its an illusion it doesnt get that much thinner.

Hummm...

I figured the aftermarket companies might go with tighter bends to keep the pipe closer to the bike and farther away from your leg.

I understand what you are saying but an aftermarket company is not going to make sharp or abrupt turns, the less bend=better flow. Longer the head pipe=lower db output.

did you guys have anyproblems with the header leaking? Ive tried instaLLing twice now and it still leaks right at the head???j wtf? I know its not as wide as the stock one where it attaches to the head. ?????

you probably need an header exhaust gasket. check ebay for one.

04-06-2009, 08:59 AM
two brothers didnt send me one with it?? do you have a gasket on yours?

Most exhaust companies ive dealt with dont send a gasket, you have to try to salvage it from your old pipe or just buy a new one.

when I took off my stock header it didnt have a gasket?? yours did? So im assuming the gasket will work for all headers?

k4f5x0r

yea same gasket for all headers. I didnt get one with my dasa but i dont think its completely neccesary. i know it has a little leak because it pops and i know its not lean. but its not a major priority.

They are crush gaskets made of a very soft metal like brass so when you tighten down the head pipe bolts it creates a much more airtight seal. If your buying a 400+ pipe spend another 3-4 to get the gasket cant hurt anything.

Two Brothers don't give you much (if any) HP over stock, but I guess you get the sound. They're the new Cobra! LOL.
