HEAT SHIELDED — KEY BENEFITS
- Lower under-bonnet temperatures: Significantly reduces radiant heat under sustained load.
- Heat containment: Keeps heat inside the exhaust path, supporting consistent performance.

- High-load reliability: Ideal for high-power, track-driven or aggressively tuned vehicles.
