two brothers exhaust on my 2007 klx 250s !!!
kawicat dont buy the big gun. ask around. it is not what you want. start a thread and ask other peoples opinions. also remember that opinions are like aholes. everyone has one, hence the big gun input. iowagay, you can say what you want but the two brothers is worth the money. double d, what is he best at? i see in your photo gallery you still have the stock exhaust so how can you even have any opinion? the stock exhaust is pathetic.
also go to the two brothers site and it has a dyno chart. you will not gain 3 hp but you will gain one from bottom and between 7 and 9000 rpm you will gain two.
Shoot I'll chime in 
As far as I know Muzzy and Big Gun are the only full systems so far
From comparative dynos I've seen from fellow klx members the BigGun provides a more constant air/fuel combustion ratio and better horsepower with the stock piston (the big gun head pipe is a little smaller than the muzzy). With a 300cc or 340 jug...... I don't know.....someone needs to post a dyno
But if you are planning a bigger jug ..... get a full system. jmho

I ALSO DREAM OF THE BIG BORE BUTMY BIKE IS BRAND NEW AND I WILL NOT GO TO THE 300CC FOR AWHILE.I ONLY HAVE 800 MILES ON IT. SEARCH THE THREADS IN THIS FORUM AND DO SOME READING. I HAVE HAD A FEW BEVERAGES SO I CAN NOT CLEARLY REMEMBER, BUT SEEMS TO ME I REMEMBER READING THAT SWITCHING TO TO LARGER HEAD PIPE WILL CAUSE YOU TO LOOSE TOURQE. I ALSO WONDER IF I COULD HAVE A PIPE CUSTOM MADE FOR THE SLIP ON WHEN I DO GO TO THE 300CC, CAUSE THE TWO BROTHERS SLIP ON COMES AS TWO PIECE, THE CANISTER AND THE PIPE ATTACHES TO IT.
I went the simple route...I got a header from FSW and then an FMF powercore IV to complement the header.I didn't get the parts on but i'm sure when i do it will be a very noticable improvement.
