Here are some preliminary pics of the first prototype rear diffuser made by Zillinois. It follows the lines of the stock exhaust and hopefully will close off the gap left from aftermarket exhausts pretty well. The front of it bolts to the differential cover and the back attaches to the bumper. This is the first of probably a few test pieces. I will be doing the initial test fit pretty soon once I get my car back from VRT next week. I want to send a HUGE thank you to Zillinois for making these, he is definately a smart guy and an awesome member of the 350Z community!

 

Looks very nice. Wonder which exhausts this will work with.

 

looks good.......cant wiat to see some pics w/ it on the car

looks better than what my bud was runnin

 

It will not be for one particular exhaust, but hopefully pretty close with all dual exhausts. I am running the new SVRTechnologies 3" dual so it will probably end up perfect for that exhaust .

 

That looks quite nasty...

 

maybe nasty, but very effective........well for a lowcost budget anyways


what makes it look so nasty tho

 

good design... but be carefull on mounting to the rear bumper (at least the stock one) this is a picture of the one i made of carbon and the force it created tore the lower bumper supports and the bumper started flapping. mabey think of a way to reinforce it somehow. just FYI

 

Looks great!

Wonder if it would work with a Nismo muffler?

 

Maybe dumb question but what does the diffuser actually do? Direct airflow for better aerodynamics?

 

could do better. I'll post pics soon.

 

Thanks for the tip spdu4ia!

Hybrid90 - You are correct. It replaces the void left by switching to an aftermarket dual exhaust.

JDMZ33 - Sounds good!

 

Now THIS is what I like to hear!

(wants a rear lower diffuser BAD!)

 

Here you go...

 

any pics of that piece installed?

 

not yet.

 

That looks pretty good to JDMZ33. Where are the mounting points? What exhaust did you fit this with? Did you do any testing with it?

 

That EVO~R one looks nice too! and plans for it in CF?

I personally am looking for something that is like the TopSecret diffuser.. except I'd have to customize it to work with my rear

 

That looks pretty nice.....bump for pics installed

 

so this diffuser won't work with stock muffler?

 

you don't need it with the stock muffler..

it's for cars that have replaced their stock muffler with something that doesn't entirely fill up that void.. what happens is, the air goes up into the void and get's caught behind the bumper causing excess drag..
