RoadsterSport SuperStreet Dual Tip Back Box

The RoadsterSport SuperStreet Dual Tip Back Box is a unique, adjustable exhaust system designed for the Mazda MX-5 ND (Mk4). It aims to blend aggressive character with refined tone control and visual appeal. This system builds on the SuperStreet Helmholtz platform, incorporating a secondary chamber in the driver's side tip for integrated acoustic tuning via a mixing baffle. Adjusting the baffle allows users to fine-tune the exhaust note, making it sharper and louder with the baffle inserted, or deeper and more bass-heavy as it's withdrawn. Constructed from lightweight stainless steel with a full 2.5-inch flow path and smooth mandrel bends, this back box is free-flowing and offers strong horsepower potential. This exhaust is intended for use with stock headers and catted midpipes. Volume levels may become excessive if used with catless setups.
