Product Description

Introducing the latest addition to the HKS exhaust series: the all-new FULL DUAL MUFFLER for the RZ34. Engineered with a straight piping layout and a 2-Way sound system, this muffler is designed to cater to your personal preferences. Compared to the stock layout with a pipe diameter of D45 mm x 2, this product features a full dual layout with a larger pipe diameter of D60.5 mm x 2. This not only allows for a substantial increase in pipe cross-sectional area equivalent to D85 mm but also ensures minimum ground clearance, which is often a concern with high-output exhaust systems. As a result, the exhaust pressure is reduced by approximately 40% compared to the stock model.

What sets this muffler apart is the inclusion of a tailpipe that connects to the sub-silencer section of the main muffler. In aggressive sound mode (without lids), it produces a sporty sound with an emphasis on the exhilarating drone. However, by switching to gentle sound mode (with lids), the sub-silencer functions as a silent chamber, providing a more comfortable and less drone-intensive sound for daily driving. With this single unit, you can enjoy two distinct types of exhaust sounds. Experience the power of the new FULL DUAL MUFFLER from HKS, designed to enhance your driving experience and deliver the perfect sound tailored to your liking.
