HKS SILENT Hi-POWER TURBO E-FC3S 13B-T

The HKS SILENT Hi-POWER TURBO E-FC3S 13B-T cat-back exhaust system is constructed from SUS304 stainless steel, a material known for its strength and resistance to corrosion, ensuring longevity even in harsh conditions. This system is specifically designed for the FC3S RX-7 with the 13B-T engine, aiming to improve exhaust flow and provide a more refined sound profile compared to stock. The large 120mm diameter muffler is a key feature, engineered to reduce backpressure and enhance exhaust gas scavenging, which can contribute to improved engine performance.

This cat-back system replaces the factory exhaust from the catalytic converter back, including the muffler and piping. The design focuses on balancing performance gains with a more controlled sound level, making it a popular choice for enthusiasts who want a noticeable improvement without excessive noise. The piping diameter is optimized to work with the 13B-T engine's characteristics, ensuring a smooth transition for exhaust gases and minimizing turbulence. Installation involves removing the existing exhaust and bolting on the new HKS components, typically requiring standard exhaust installation tools.

When installing this system, it's important to ensure all connections are properly sealed to prevent leaks, which can affect performance and sound. The SUS304 stainless steel construction means this exhaust should hold up well over time, resisting rust and maintaining its appearance. This cat-back system is a significant upgrade for the FC3S RX-7, offering a blend of performance, sound, and durability from a well-known manufacturer in the import performance market.
