HKS Hi-Power Cat-Back Exhaust with Titanium Tip for Mazda RX-8 (Series 1 & 2, 2003-2012)

HKS has long been regarded as one of Japan’s most respected performance exhaust manufacturers, and this Hi-Power Cat-Back Exhaust is a standout option for the Mazda RX-8 Series 1 & 2 (2003-2012). Built with 75mm SUS304 stainless steel piping, a 97mm burnt titanium tip, and a straight-through high-flow layout, it is designed to improve exhaust efficiency, sharpen throttle response, and deliver the crisp, high-revving sound rotary enthusiasts love.

• Features 75mm SUS304 stainless steel piping for excellent flow, durability and corrosion resistance
• Finished with a 97mm titanium burnt blue tip for a premium Japanese performance look
• Uses an offset muffler design to improve exhaust flow and support high-RPM performance
• Built with a straight-through internal layout to reduce backpressure and improve throttle response
• Produces a deep idle tone and crisp rotary scream at higher RPM without excessive drone
• Designed as a direct bolt-on cat-back system with clamp and mounting hardware included
• Constructed to a very high standard and now discontinued by HKS, making remaining stock especially desirable
• Delivers a rare combination of strong flow, premium finish and authentic sound for discerning RX-8 owners

You will notice a more responsive, freer-breathing engine, a stronger top-end feel, and a more authentic rotary exhaust character that works well on both the street and during more spirited driving.

For a more complete exhaust package, consider pairing this system with the ODULA Stainless Steel Exhaust Manifold, HKS Metal Catalyzer, CUSCO Strengthened Exhaust Hangers and the ODULA Racing Exhaust Earth Strap Set for a stronger, better-supported exhaust setup.
