The Nismo bumper is flatter along the bottom near the grille. I've got the ducts like Rusty, and even though the fit the bumper perfectly, I did need to secure them with screws.

I had to use screws as well.

I bolted mine on with painted stainless and self-locking nuts on the inside.

How did you mount your reducers to the revotecs? Glue?

And gorilla grip tape

2 part glue.

Hi Dlo! Ran into you at Autoclub Speedway! Thanks for the heads up about this link! I am def, going to look into this upgrade for my Nismo

^ Excellent. Synolimit did these ducts and used the 3" inlets instead of the 4" inlets I used. I actually like the 3" better. I posted a link to the 3" to 2" reducer a few posts above. Either way you go won't let you down I'm sure!

Great driving BTW at ACS.
