Does Yoshimura make a full system for the F4I?
 

I have seen a few places selling Yoshi full systems for the F4I, But Yoshi doesnt list a full system on their site for the F4I. Are these true Yoshi systems for the F4I or miss titled systems for the RR maybe? anyone know?

Yes they made a couple of different full systems for the F4i. They don't produce them anymore but there is still quite a bit of stock which is why you can still find them for sell. They dont make the Yoshi EMS for them anymore either but they still make it for several 4 wheelers and i think some newer bikes.

Put the titanium one on my bike last year.

thanks for the imput. Is the full system worth the extra cash vs. a slip on and saving some cash. Im more interested in sound quality then horse power. I was thinking of the TRS stainless package. Im not a big fan of carbon fiber.

If your looking for sound and not hp, then save yourself the money and just get a slip on. If you don't have your bike dyno'd then it won't get the best performance posssible.

I've got the Yoshi TRS carbon fiber on mine and I'm pretty happy with it. CF matches the black frame. Also it doesn't get hot to the touch, so less risk to a passenger should I ever decide to get one...

+1 For the sound alone, a slip on is all you need. If you go full system you will need a PCIII. When I got mine, I got feedback from a lot of people that had done it that I should re-gear also. I went -1, +2 and that took away any low end power loss I may have experienced. Not sure how much I would have had, as I did the mod when I did the exhaust so I have no comparison.
