Code No. 31014-KN002
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.

About HKS muffler
*1: About center pipe
Diameter of center pipe is the portion that has the largest diameter. (Excluding silencer and tip.) It is the condition with stock suspension.
*2: Minimum road clearance between HKS muffler (Any parts included in the kit) and road surface. Therefore, it may be different from actual road clearance of the vehicle.
The data is basically the condition with stock suspension. However, please understand that some items have data with low down spring or ride height adjustable suspension kit.
Caution: Hook, bracket, stay may be changed without prior notice.
★ Exhaust noise level at idle.
