The HKS Metal Catalyzer enhances exhaust efficiency for the Mazda RX8 Series 1 (2003–2008) 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.
- Features a high-capacity metallic substrate for superb heat resistance and longevity
- Reduces exhaust backpressure for faster throttle response and improved mid-range pull
- Direct bolt-on fitment for straightforward installation
- Pairs exceptionally well with the GREDDY TRUST GT Slash Exhaust
- Withstands high thermal cycles thanks to robust construction
You will experience a smoother, freer-revving engine character with improved drivability and a more responsive feel.
For an optimised setup, consider combining with the AUTOEXE Ram Air Intake or the KTS Induction Tube.
