ok i got a 03 zx6r, it has about 14k miles on it, (8K) when i bought it, anyways its been maintained well with synthetic oil , new filters , 2bro slip on and pcIIIusb. i was looking for a header but 2 brothers dont make one for my bike but i heard the stock header is ok since we dont have a cat or anything blocking airflow. so what would be my best bet in terms of being around 115 to 120 hp. would it be best just to get it dyno tuned and leave it at that. b.c eventually thats where its gonna end up . anyone had any experiences with anymiddle tennessee dyno shops.

 

its a guy in fayetville, tn name Dan Marrs thats dyno tuned alot of my bikes, great guy and the prices are right, but u should be around 115 or so hp now with the mods u got, these bikes made 111hp from the factory at the rear wheel

 

Get a PC 111, an ignition module (or the Race Kit ECU; PC111 & IM in one)& a K&N or BMC filter. These bike make a lot of power just by a little ignition advance with a custom map. You are correct about the headers but if you want better flow & more Top-End power, Yoshimura, Muzzys, Leo Vincemakes a full system.
