I want to put undertail exhaust on my f2..or the cheap moto gp exhaust but im afraid of not enough compression with the gp and would like to see some pics if anyone has done the undertail on an f2 rear end I have an extended swing are and considering running my pipe between the swing arm and tire????? thoughts and pictures greatly appreciated!!! thanks nate

 

I would love to what you have in mind. I've thought about it but I don't want to ruin my bike because it is 100% original!

 

It's been done before. The difficult part is doing the custom pipe welding to route it properly. From there I'd say the next most difficult part is to properly heat shield your ***** and @sshole from the exhaust pipe. Next ups is making sure it clears properly when your suspension is fully compressed.

Back pressure is last, but I imagine that won't be such a big deal.

 

did you ever get it done?
