The GREDDY TRUST GT Slash Exhaust System gives the Mazda RX8 Series 1 & 2 (2003–2012) a deeper, smoother tone while improving exhaust flow for enhanced performance. It delivers a refined, drone-free sound that complements daily driving and spirited use alike.

  • Produces a clean, resonant exhaust note with no harshness
  • Improves flow characteristics for better high-rpm performance
