Description

The HKS Silent Hi-Power cat-back exhaust system is built for the turbocharged Mazda RX-7 FC3S (13B-T). The 75mm mandrel-bent center pipe is SUS304 stainless steel and exits through a single 120mm HP (TYPE-H) tip on the driver side. A silent chamber in the muffler cuts low-frequency cabin drone while the straight-through structure keeps performance intact, measuring 99 dB close and 87 dB at idle per HKS catalog data.
