also what is schira talking about when he says get a pc and a map for it?, im completely unfamiliar with any lingo and abbreviations at this point, good knowlege baxsom btw that helped alot

 

I have a Two Brothers slip-onon my 07' 1000 and I couldnt be happier. A friend has the full Yosh on his 1000 and it doesnt sound far from stock, can't sey what it did for the power. My friend with 07' REPSOL has the Titanium Akro which sounds GREAT, but not asDEEP as my Bro's. On the same DYNO, the full Akro only produced 3.96 more pornies than my slip-on 2 Bro's. About $1000.00 difference in price as well, to the Akro. The 2 Brothers I have on my PRECiOUSis the exact grunty, deep like ocean depths, GROWL I was looking for.

A POWERCOMANDER taps into the bikes computer and controls the fuel distribution. The POWERCOMANDER can be plugged with different "MAPS" according to what exhaust you have, if you have an aftermarket air filter ect. POWERCOMMANDER with smooth out the bike and give it a more even pull through the rpms

 

then that was a ****ty tuner because on the 1000RR's that you mentioned the two bros slip is good for about a 5hp increase while the akro should putting down an extra 10-15 when tuned properly
dont believe me
go to a 1000rr only forum like www.1000rr.net and ask if the full akro is as good as the 2 mothers slip on. then prepare to get laughed off the board

besides isnt this a 600 forum

dont listen to everyone
do the research
look for dyno charts
dont believe anyone that doesnt post a dyno chart showing a baseline showing how much the bike started with and how much the pipe plus map net gained

 

Here is my two cents on this one. Unless you are racing you probably won't even notice the difference. I had a 04' F4i with full Arrow exhaust and it dynoed at 104 (stolen: Rest in Pieces). My current 04' RR has a two brothers slip on and turned 101. Two Brothers can be annoying it is so loud...wish I had anything but that on it.....personal preference.

 

Go with thecoolest looking one, the biggest, baddest, coolest looking one

 

I run an erion racing exhaust. Erion is kevin erion the other brother of two brothers racing. The exhaust is louder than stock but not as loud as the two bros. Its a bit more expensive but the quality is excellent, welds are perfect and im a welder. Also everyone and there mothers have a two brothers. People all say its great but how many exhausts have they really tried ? I have riden f4i's with a few different exhaust and IMO i like my erion the best.

 

"Everyone and their mothers have a two brothers"

haha i like that.

 

two brothers = large fart can

you want power go with Arata, akro. or KR Tuned

 

I have the option of purchasing a new bike with the erion slip on, tank proctor, tank cap proector, chrome wind shield, and i think a fender eleminator for about $1000 more than a stock bike.
$1000 sounds alot to me. $9200 total for the 07 600rr.
For that kind of money I could buy a gsxr 750 and have 30 more horsepower and a bike the weights the same.
So somebody tell me why you purchased a honda 600 knowing the 750 has 25 to 30 more hp and weights close to the same?

i think yoshi has a cleaner look and sounds real good the 2bros is good too but im not into how it looks but my oppinion but its all in the oppinion but as far as bolt on or slip on slip on is basicly for sound not muh more power but the bolt on i think its a good idea to get a pc3
