Dual Hi-Power Titanium Tip Cat-Back Exhaust

• 2023-2026 Nissan | Z

The HKS Dual Hi-Power Cat-Back Exhaust for the 2023-2024 Nissan Z (RZ34) is a new full dual muffler system designed with a straight piping layout and a 2-way sound system you can adjust to your taste. While the stock layout uses D45mm x 2 piping, this system runs a full dual D60.5mm x 2 layout - securing a pipe cross-sectional area equivalent to D85mm while keeping the exhaust at the minimum ground clearance so common on high-output exhausts. Exhaust pressure is reduced by around 40% compared to stock. The included tailpipe on the sub-silencer section of the main muffler delivers a sporty sound with an emphasis on drone in aggressive sound mode (without lids); in gentle sound mode (with lids), the sub-silencer acts as a silent chamber for comfortable sound with less drone in daily driving - one system, two exhaust sounds.
