HKS Full Dual Muffler for RZ34 Nissan Z

The HKS exhaust series has now introduced a completely new FULL DUAL MUFFLER for the RZ34. It features an efficient straight piping layout, alongside with a highly desired 2-Way sound system that can be tailored to your preferences.

D60.5mm x2 – Full Dual Layout

• This product has two pipes, each with a diameter of 60.5mm; in comparison, the stock layout features two pipes at 45 mm in diameter

• This permits a pipe cross-section size of D85mm to be attached while still providing the minimum ground clearance commonly seen in high output exhausts

• Compared to the stock model, exhaust pressure has been decreased by approximately 40%

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 enables the user to experience two types of exhaust sounds
