Skip to product information

Features & Benefits

    The most free-flowing option in the JBA muffler catalog, this ultra-compact 6" straight-through design functions more like a high-performance resonator than a traditional muffler — minimal restriction, maximum exhaust velocity. Available in a 2.5" center/center configuration, it's ideal for race builds, secondary resonator positions, or any application where flow takes priority over sound attenuation.

    • Dimensions - 6" x 6" x 4"
    • 2.5" center in/out
    • Straight-Through: Sound passes through a perforated core packed with sound-absorbing material. Less restriction, more flow, raspier/higher-pitched tone. Better for performance-focused builds.
