The NB Mazda Miata diffuser was created for those who want to maintain the structure of their rear bumper. The diffuser is easy to install and comes in two styles - full width and narrow. Pictured is our shop's 2004 NB Mazda Miata with a narrow width diffuser and underbody extension installed. It has a Magnaflow Exhaust.
The narrow width diffuser stretches to the inner edges of your single or dual exhaust tips. As opposed to the full width diffuser, you are able to run an exhaust with tips over 3" in diameter with this set up. Each fin is 3.5" long meaning there is lower ground clearance in the rear.
Both NB Mazda Miata Diffusers are supplied with a flat underbody tray that extends under the Miata's rear muffler and utlizes existing bolts in the rear subframe. If your muffler is much larger than the Miata's stock muffler, or isn't in the same spot as the stock muffler, you run the risk of contact with the diffuser. Give us a call if you're worried and we'll see what we can do on our end. The diffusers are also made to allow for use of both stock towhooks.
