I currently have a 2013 infiniti g37x sedan and I am looking at getting a new bumper after someone back into me . I noticed the q50 has a very unique bumper and was wonder if anyone found or tried to modify a q50 bumper for a g37?

 

Anything can be done with enough money. But the Q50 is a totally different platform and it would take a lot of work to fit its bumper to a g37.

 

You could look at a Sport bumper as a replacement, plus or minus optional front lip. I think it looks much better than the normal Journey/X bumper, and it would have OEM fit/finish. You might have to wire fogs if you don't have them though.

I don't know of any aftermarket bumpers for 2010+ sedans from reputable producers.
