A new FULL DUAL MUFFLER for the RZ34 has become part of the HKS exhaust series.
It is designed straight piping layout with 2-Way sound system for your taste!

D60.5 mm x 2 Full Dual Layout

While the stock layout has a pipe diameter of D45 mm x 2, this product has a full dual layout with a pipe diameter of D60.5 mm x 2.This allows a pipe cross-sectional area equivalent to D85 mm to be secured while lowering to the minimum ground clearance, which is often seen with high output mufflers. Exhaust pressure is reduced by around 40% compared to the stock model. This layout is designed for both daily use and performance.

2 Way Sound System (Gentle Sound Mode & Aggressive Sound Mode)

By adopting the included tail pipe to the sub-silencer section of the main muffler, there is a sporty sound with an emphasis on drone in aggressive sound mode (without lids). By gentle sound mode (with lids), the sub-silencer functions as a silent chamber and can be switched to comfortable sound with less drone in daily driving. This single unit allows the user to enjoy two types of exhaust sound.
