I just traded in my 2000f4 with all the bolt ons in on a new 07 cbr1000rr. Just a reference that i had an f4. But to the story. My buddy has a 99f4 with jus a dnd slip on. My srt4 has mopar stg3 without toys. With hksbov,quickwhips intercooler,jmb pressurepipes, boomba motor mounts, gutted cat, 3inch exhaust, aem intake. Never took it to the track. So we ran from a 40 roll n he pulled acouple car lengths and i couldnt close it. We ran from 60mph we ran neck and neck all the way to 140mph. i was surprised my car could keep up.
