No you do not have to remove or modify the crashbar to install the Cyber Kit as it is a USDM kit, BUT there are kits like this one that are JDM and yes you do have to modify your crash bar. The only way you'd have to remove/modify the crash bar is if it is a JDM-made kit or bumper..
So no you do not have to remove the crash bar, unless it's molded off a JDM mold.. Hopefully this'll answer your question!
