Free up exhaust flow with a high-flow metal catalytic converter that reduces backpressure, sharpens throttle response, and supports future tuning without harsh drone.
$2,600
The HKS Metal Catalyzer enhances exhaust efficiency for the Mazda RX8 Series 1 & 2 (2003-2012) with a high-flow, heat-resistant metallic core that reduces restriction while maintaining emissions compliance. The result is smoother, more responsive power delivery across the rev range.
You will experience a smoother, freer-revving engine character with improved drivability and a more responsive feel.
For a more complete exhaust package, consider pairing this with the ODULA Stainless Steel Exhaust Manifold and your choice of the GREDDY TRUST Comfort Sports GT Slash Exhaust System, AUTOEXE Premium Cat-Back Exhaust Muffler or HKS Hi-Power Cat-Back Exhaust for a freer-flowing, more cohesive Japanese exhaust setup.
