Extended throttle cable. Heli-Bars

I'm installing Heli-Bars on my 96 VFR and Im wondering if anyone knows if Honda makes a throttle cable that is about 2 inches longer than the stock throttle cable.

I know the conventional solution is to re-route the cable, but like Frank Sinatra, I'd rater do (muck it up) my way.
