i am getting a two bro's slip on for my 600rr do i need a power comander with just a slip on pipe? i dont want it to run to rich

 

no need for power commander. Get one later when you can . I have 07 with same pipe, load as hell but sounds awesome.

 

had an 04 cbr600rr with two bros loved it bad *** sound put power commander on it deff more power and better performace now got an 08 with two bros no power commander still sounds awsome

 

so i dont need one but "if" i want more power witch i do i should get one? Next year i plan on buying a new CBR its all i ride

 

a power commander is not going to get u more power. i dont consider 1 or 2 whp extra really, they aren't made for that. they're made to smooth out your power curve, not for actual power per say.
if you need one get it, otherwise what's the point other than wasting money?

 

ok. i have never had a power commander on my bike before so i never really knew what they did but i do no so thatnks for all the info

 

I have a two-bro's slip on my 03 without a powercommander... it was running a bit rich so to even it out i bought a k&n and it doesn't run rich anymore.
