I think you'll find yourself needing a new rad before too long. So I think no.
not a fan myself but if you wanted it to look like that then you can get black mesh type stuff to put there.I dont like the stripe, wonder how hard it is to merge a ph2 and ph1 bumper, like the top half off the ph1 so it fits on and the bottom half of the ph2.
Anyone ever done this before??
I wouldnt leave it completely open, would maybe put honeycomb grill in place, jus think a big open mouth would look pretty cool!!
