Q: Mid pipe needed??
Over 10 months ago
Does this exhaust need a mid pipe? I realize it has a header and a slip on but is there a mid pipe needed?

Q: Is a fuel tuner required for a 2014 crf450r?
Over 3 years ago
i have a 2014 honda crf450r and have heard if you change exhaust you need to get a programmer to adjust the mapping i ride alot at sea level and in the mountains. also do you have to replace the side panel to fit this exhaust?

A: You do not have to replace the side panel with this exhaust. Being a single, you will only have the exhaust on the RIGHT side of the bike. UFO does make an optional left side panel that is flatter for use with the single exhaust.

Normally when installing a slip-on only minor changes to the air/fuel ratio are needed, if any at all. If your bike is currently running properly, likely you will not have to make any changes after installing this slip-on. I would recommend installing the exhaust and riding the machine to see how it is running then decide if you need an purchase an aftermarket EFI tuner .
