Hi there!

New to the forum, just bought my first bike and lovig my new 05 candy/silver f4i! Im looking for a slip on and I have pretty much narrowed it down to a yosh. I got a few questions that I havent been able to find answers on and hope you guys could help.

I take it the slip on will have all the bungs/attachments for any 02 sensors that are on the stock tube?

All this talk of using a power commander or remap.....is it necessary for a slip on?

Any other help is appreciated!

 

If its just the slip on can your getting, you get all the other bits and pieces to connect it to the bike securely. There are no sensors in the exhaust system (but then my bike is a UK model not sure about US models so wouldn't know).

Power commanders are not really necessary for a slip on can, but it is advised. You'll find that the exhaust will run either rich of lean at different points through the system, so the power commander and dyno time makes sure everything is running as it should be. Also having the right fuel map for your can and bike will give you a little more BHP and give you the full potential of the set-up.

My friend has a yoshi can on his R6, its made it run stupidly rich and his fuel consumption has gone from 140 miles a tank to 90 miles a tank. Not sure what effect it has on an f4i though?

Hope this makes sense :P
