HKS SILENT Hi-POWER TURBO E-FC3S 13B-T Mazda RX-7 1986-1991

HKS Silent Hi-Power Turbo is a full cat-back exhaust system built for the Mazda RX-7 FC3S 13B-T turbo engine from 1986 to 1991. This setup replaces the stock exhaust from the catalytic converter back to deliver smoother turbo spool, higher horsepower and torque gains through improved exhaust flow. It maintains low noise levels ideal for street driving while unlocking rotary performance potential.

Key Features

  • SUS304 Stainless Steel: Full construction resists corrosion and withstands high heat from turbo applications for long-lasting durability.
  • Mandrel-Bent Piping: φ60.5-80-80x2 mm diameter optimizes exhaust gas velocity for quicker turbo response and power delivery across RPM range.
  • Polished Single Tip: φ90 mm x 120 mm tip adds clean aggressive look to FC3S rear end without excessive drone.
  • Lightweight Design: Weighs 11.0 kg, cuts over 7 kg from stock exhaust to improve handling and acceleration feel.
  • Hi-Power Flow: Enlarged volume boosts output by up to 10 ps while Silent chamber keeps sound under Japanese noise regulations.

Product Notes

  • Direct bolt-on replacement for stock cat-back on FC3S 13B-T models.
  • Inspect turbo downpipe connection during install for best sealing.
  • Packaged in original HKS box to prevent shipping damage.

Installation Notes

  • Professional installation recommended.
  • Bolt-on fit using factory hangers and mounts, no fabrication needed.
  • Compatible with stock catalytic converter and O2 sensor location.
