Description

The RoadsterSport Super-Q Dual Tip Back Box is a refined muffler system for the Mazda MX-5 ND. It delivers a deeper tone without excessive volume or cabin drone, making it ideal for daily driving. The system features a triple-chamber internal layout with a precisely tuned Helmholtz resonator to cancel midrange drone frequencies.

Constructed from 304 stainless steel with mandrel bends and precision welds, this back box weighs 10.9kg (24lbs) and includes dual polished rolled tips with a side-entry flow design.
