is it worth it?

what will I see performance?

I have a PCIII that should help.

thanks

just a little input....i had a yosh slip on....sounded alright....but i too wanted a little more hp. so i bought a bmc filter and a full hindle high mount and a power commander 3...the only thing i had prior to these was a tre....i installed the full hindle and i havent gotten around to installing the power commander or the bmc filter....ill tell you that the mid range is torque is very impressive....very noticable gains from a slip on to a full system. and i havent even mapped it yet.

full acra is worth ten hp over stock garanteed. need to re-map powercommander to get the most out of your mods!!

I have a o1 gsxr 1k I went from 146 hp stock. I put on a full Akra , K%N , Power commander, treand par mod . It now dynos at 162 hp
