This rear diffuser slides over your stock early NSX (1991-2001) rear valance, and secures using double sided tape, and two screws which thread into pre-existing holes. The installation requires no drilling, no modification of your stock lower valance, and is easily reversable. This rear diffuser is offered in either carbon fiber (as pictured) or fiberglass, which matches the color of the stock rear valance, or is suitable for paint, to simulate the appearance of the '02+ rear valance.

This rear diffuser does not restrict the tip diameter of your exhaust system, by installing this item, paint matched to your NSX, you can have a quad-tipped exhaust and still maintain the appearance of the newer rear valance. Alternatively, in Carbon Fiber, it makes the rear of the car look much more-aggressive, and completes the look of adding an NSX-R rear spoiler.
