Thank you. You have rated this product.

A fully functional diffuser for the ND Miata that reduces lift, reduces drag, and looks great too. We're big fans of aerodynamic parts that WORK, and Velox motorsports designed this unit in CFD specifically for the ND. If you're like us and want to geek out over all the technical details, you can view the full write-up at the link at the bottom of this page.

The unit is adjustable vertically to fit multiple aftermarket exhausts. Produced from aluminum, the unit can take quite a beating and still retain it's functionality and shape.

FITMENT NOTES: Fits with all of our RoadsterSport muffler options EXCEPT the Twin Tip Super Street. To fit this diffuser with the TTSS, you will need to add longer hardware with additional spacers to space the diffuser down enough to clear that muffler.

Stainless hardware throughout
All brackets/hardware included for a full install

Design Features:
Organic Shape
Flat head riveted strakes (No rivet heads visible, flat bottom)

Good morning Brian, I finally got a chance to put the exhaust on, great advice, it's just loud enough, solid product. I'm running without the baffles, sounds great in power band. Take care, you have all my future upgrade business.........regards.

I received the Roadstersport II, and I wanted to compliment you guys on an awesome product. The Miata should have these on from the factory. They make a great sound, that is not obnoxious at all. The exhaust also installed seamlessly!!! I will buy all of my Miata stuff from you in the future. Thanks,

-- Nate
