• Integrated high-flow metallic core (200–300 cell density) provides reduced restriction while maintaining catalytic efficiency

• O₂ sensor bungs positioned for OEM sensor reuse

---

Performance Benefits

• Significantly lower backpressure versus OEM converters

• Gains typically range from 5–12 horsepower, depending on supporting modifications and ECU calibration

• Noticeably deeper and sharper exhaust tone without excessive cabin resonance

• Weight savings compared to stock catalytic assemblies

• Designed for optimal balance between sound, performance, and emissions control
