The Borla CrateMuffler Resonator Option is a compact, universal resonator for 2.5in systems that reduces sound pressure by roughly 2–3 dB(A) without degrading flow. Constructed from T‑304 stainless steel with 100% welded construction and CFF acoustic fiber, its straight‑through design preserves performance. The reversible layout and un‑notched necks provide installation flexibility for tight spaces and can be welded or clamped as required.
