I have a 2013 g37 Diffuser with that ugly lower bumper ridge. I would like a diffuser that reaches the middle of the license plate and tapers at the outer edges for my rear exhaust pipes. (See in the pics with the Green Check mark.

Can anyone recommend me a diffuser. Please provide links to where I can order it.

2013 g37 Diffuser

 

Good thing you put the checkmarks or I don't think I would have noticed the difference!

I think the only diffuser available might be the carbon signal one? There are not many.

 

It's not so much the bolt-on part you need as it is you bumper that makes it happen. You want the 2007 - 2009 Sedan rear bumper.

 

I was told that the earlier model bumpers would not fix because the rear of the 2013 is slightly bigger..

 

AFAIK, it's a direct swap.

But don't take my word for it. You can research it here, or over on G35Driver for the '07-'08 model years.

 

It does fit. The sheetmetal has never changed

 

Thanks Gents, but I'd rather not change my entire Bumper.. that'll cost me at least $1,500 for Bumper with pearl paint and diffuser. I'm "Ballin on a Budget" over here guys.. I hoping someone can help me out with this..

 

The top right diffuser (the top right photo and the gold G37 both have the same diffuser equipped, just paint matched) is the Carbon Signal diffuser and should fit...however if you aren't willing to pay the $1500 to swap the bumper to a 07-09 rear bumper, I doubt you're willing to pay for the Carbon Signals parts, as you'll be well over $1000 after shipping on those.

Carbon Signal Rear Diffuser

As Rochester mentioned, the bumper that curves down right around the exhaust tips is the 07-09 G35/G37 bumper. It is a direct fit to the 10+ G37 sedan, however you will need to drill out holes in the bumper to mount the rear parking sensors, as earlier models were not equipped with them. Otherwise, your options are to vinyl wrap that section to make it look like you want, but honestly that looks really bad with the extended curves of the 10+ bumper.

Those are really the only options you have to do what you want...

 

The top right picture with the white sedan has the Access Evolution diffuser. Its $1500 before shipping. During the group buy the Carbon Signal fiberglass version was definitely cheaper at $800 shipped.
