Pit Crew Racing | Hand Bent Special Exhaust Muffler for Mazda MX5 Miata NC
Pit Crew Racing | Hand Bent Special Exhaust Muffler for Mazda MX-5 Miata NC
The Pit Crew Racing Hand Bent Special Exhaust Muffler is engineered to deliver measurable performance improvements while maintaining refined sound characteristics. Testing was conducted under identical conditions comparing the factory setup with a configuration using this muffler and the Pit Crew Racing exhaust manifold. By standardizing the measurement environment and minimizing variables, testing confirmed a power increase of over 20 horsepower.
Developed with a focus on creating an exhaust that truly performs, the silencer design was carefully refined. Capacity, internal perforation diameter, quantity, and arrangement were all optimized to achieve the ideal balance between exhaust flow and backpressure. The result is an exhaust system that allows the engine to rev smoothly at high RPM while maintaining strong low-to-mid range torque.
The outlet features a bullet-style tapered design, which helps suppress the booming resonance commonly experienced in convertible vehicles. This produces a crisp, sporty tone during acceleration while maintaining a clear and unobtrusive sound during cruising.
Designed with competition-level performance in mind, this muffler prioritizes exhaust efficiency while still maintaining driver comfort.
