This is a high quality custom rear diffuser for the Mitsubishi 3000GT & Dodge Stealth. It is CNC cut from 1/8" aluminum, precision formed and TIG welded. It wraps all the way around the fuel tank and ties right into the rear bumper. It works with the stock exhaust and most, if not all aftermarket exhaust setups. Installation (though recommended to be done by a professional) is fast and easy. It takes no modifications to the car, not even drilling; all of the needed hardware is included. In a matter of 30 minutes or so this diffuser leaves the back end looking clean but aggressive. Diffusers are used in most racing venues and below is an excerpt from Wikipedia that describes the theory behind a diffuser.
*If installing on a car with aftermarket exhaust some trimming of the diffuser may be required*
When a diffuser is used, the air flows into the underbody from the front and sides of the car, accelerates and reduces pressure. There is a suction peak at the transition of the flat bottom and diffuser. The diffuser then eases this high velocity air back to normal velocity and also helps fill in the area behind the car making the whole underbody a more efficient downforce producing device by reducing drag on the car and increasing downforce.
