HKS Full Dual Muffler Catback Exhaust System - Nissan 400Z RZ34 VR30DDT

Introducing the latest addition to the HKS exhaust series - the all-new FULL DUAL MUFFLER designed specifically for the RZ34. This muffler features a straight piping layout with a unique 2-Way sound system, catering to your preferences.

The D60.5 mm x 2 Full Dual Layout sets it apart from the stock version, which only has a pipe diameter of D45 mm x 2. This upgraded design ensures a pipe cross-sectional area equivalent to D85 mm while maintaining a minimum ground clearance. As a result, it effectively reduces exhaust pressure by approximately 40% compared to the stock model. This thoughtful layout is optimized for both daily use and performance, making it an ideal choice for any driving scenario.

The standout feature of the 2 Way Sound System offers a versatile acoustic experience. In the Aggressive Sound Mode (without lids), the inclusion of a tail pipe to the sub-silencer section of the main muffler produces a sporty sound with a noticeable drone, adding to the thrilling driving experience. On the other hand, the Gentle Sound Mode (with lids) utilizes the sub-silencer as a silent chamber, resulting in a more subdued and comfortable sound with reduced drone during everyday driving. With this innovative design, drivers can easily switch between these two distinct exhaust sound profiles with a single unit, enhancing the overall driving pleasure.

There is no change in minimum ground clearance with the installation of the product. Compatible with both 9AT/6MT.
