I just got the HorsePowerFreaks front mount, does anyone know what you have to cut to make it fit? And does anyone have the Beatrush undertray with the HPF / big intercooler?

 

The intercooler is a bolt-on that does not require you to modify the bumper support. Mitsu tolerances on the molding of the back side of the Evo IX fronts seem to be pretty slack so you may need to slightly trim the bumper cover (very very minor if at all) for perfect clearance. The factory undertray will go on without issue though we've not installed the intercooler onto an Evo with the Beatrush undertray. If you have any questions during install don't hesitate to call, E-mail or send me a PM.
