I want to get an M4 slip-on exhaust for my '09 six. I am unfortunately pretty much a noob as this would by my first aftermarket exhaust. Ive been doing some research, but I think you guys are the best to ask. Do I need a power commander to change the fuel map with a slip on or is that only...

I'm about to by a power commander V for my 07 zx6r. And can't disside if I should get the auto tuner along with it. Does anyone else have it? Is it worth it?!!!!:O

I have a 07 zx6r. Should I get the 3 or is the extra money worth geting the 5?

So im still looking for a map for my bike as follows: 2005-06 zx636 H&N Air filter Yoshimura RS-5 slip on otherwise stock Does anyone have one? or know of one? the Dynojet website doesn't have any for a yoshi Slip on Cheers, Dane
