I am still looking for those Cforce folks who know or have done Exhaust upgrades, or added fuel controllers. I just want to know is it any available out there for these type? I would like to have a better sound and  throttle response.

Link doesn't seem to work.

It works. That's pretty shiny. Didn't see how much.

Thanks for link, has anyone tried it yet on there Cforce? Or any videos showing them in use?

Plus if these work for the 550 it should work for our 500??? I believe someone said there are the same.

Yep, 500 ho and 550 are the same. I did notice there are some without EPS but haven't seen any myself.
