HKS Hi-Power Cat-Back Exhaust System - Mazda RX-8 SE3P (2004-2008)
The HKS Hi-Power Cat-Back Exhaust System is designed for the Mazda RX-8 SE3P, delivering improved exhaust flow, a sporty exhaust note, and long-lasting durability. Engineered to help the engine breathe more efficiently, it is suitable for both stock vehicles and higher-performance builds where increased exhaust flow can support additional engine modifications.
The rear muffler and exhaust tip are manufactured from SUS304 stainless steel, providing outstanding corrosion resistance, long service life, and a premium finish. The main exhaust piping is constructed from S409 stainless steel, offering excellent heat resistance and durability for demanding driving conditions.
The straight-through muffler design reduces back pressure and improves exhaust flow, allowing the engine to operate more efficiently across the rev range. The result is improved throttle response and the deep, sporty exhaust note that defines the HKS Hi-Power series while maintaining the quality and durability expected from HKS.
The system features a single-exit configuration and includes an adjustable titanium exhaust tip, allowing precise adjustment of the tip position for optimal fitment and a premium appearance.
