HKS Super Turbo Muffler Exhaust System - Mazda RX-7 FD3S (1993-2002)
The HKS Super Turbo Muffler Exhaust System is designed for the Mazda RX-7 FD3S (1993–2002) equipped with the legendary twin-turbocharged 13B-REW rotary engine. Combining maximum exhaust flow, low back pressure, and refined acoustics, this system delivers exceptional performance without compromising everyday driving comfort.
The Super Turbo Muffler series was developed around three key objectives: maximum exhaust efficiency, reduced sound pressure, and an engine-specific exhaust note. The result is an exhaust system that performs equally well on stock vehicles and high-performance builds equipped with upgraded turbochargers.
The optimized design improves exhaust flow and reduces back pressure, allowing the turbocharged 13B-REW engine to breathe more efficiently. This results in quicker turbo response, improved throttle response, and a broader, more usable powerband while maximizing the engine's performance potential.
The exhaust note has been carefully engineered specifically for the rotary engine, producing a deep, sporty, and distinctive sound. During normal driving, the system remains quiet and refined, while the unmistakable RX-7 exhaust note comes alive under acceleration and at higher RPM.
The exhaust system also meets JASMA noise regulations, making it an excellent choice for enthusiasts who want outstanding performance while maintaining legal sound levels and everyday comfort.
Manufactured from high-quality stainless steel, the system provides outstanding corrosion resistance, excellent heat resistance, and long-lasting durability. Designed as a direct bolt-on replacement, it offers OEM-style fitment for straightforward installation.
