Yep...DC 4-1 header rubs front crossmember and vibrates annoyingly while driving. Has been doing it since installed but now is worse since i put all the prothane mounts in (that's a whole nother vibration story ).

Anyway...anybody else have this problem? Did you guys just bash in the front CM? What header you using?

yes you have to notch the crossmember to run a 4-1
