The ARC Performance Diffuser is a one-of-a-kind aero piece constructed of high grade aluminum. Serious circuit use was in mind when being developed and real improvements can be experienced. Not only this but you will definitely stand out from the rest of the growing Z33 crowd.

*This ARC Diffuser has been designed for use in conjunction with ARC Silencer Exhaust Mufflers.
