So new member here, and well my gf has a 2010 G37 base coupe that she (okay, we) are looking to put a little bit in to and I'm just hoping you guys can steer me in the right direction.

Not trying to get too crazy, probably just intake and exhaust at some point, and well she's more into the exterior mods. Which leads me to my first question, where can I find some aftermarket grilles? It looks like she got backed into by a truck with a hitch and her stock grille is all cracked up now. So of course if I'm gonna fix it, why not change it up a little? Oh and she is looking to tint her windows so if there are any members here that know where to go around SoCal (San Clemente, specifically) let me know as we are new to the state!

Any links and/or help is appreciated.

For just a deeper tone and nice looking tips you can check out the TopSpeed or Beluga axleback exhaust, just be sure to get the beveled tips.
For grills, the OEM "midnight grill" is nice, just has the center in black. There's also the Cmod grills, these need to be paint matched
