wait, so you mean keeping the standard exhaust tips in the same place, but then adding a third larger pipe in the middle where the mesh is? yes, that would look terrible.
however if you did a single exit exhaust through the middle (either 3 separate tips like the Ferrari F40, or one massive trapezoidal one, like a lambo aventador) and then modified the bumber so there was no evidence of the old exhaust cutouts, I think that would be ok.
Anyone fancy photoshopping the below image so we can see what it might look like with one big central exhaust, and none at the sides? or both?
