YOSHIMURA RS4 Stainless Steel for Suzuki DR‑Z 400 (manufacturer part number 116600D320): a complete competition-oriented exhaust line that combines technology from professional motocross and racing aesthetics. The RS‑4 silencer features a carbon cap and an aluminum body, mounted on a stainless steel pipe that withstands thermal stress and intensive use.

• Compact design and aluminum/carbon finish for a sporty roadster look.
• RS‑4 silencer with dual chamber: a two-chamber system offering progressive sound insulation and exhaust pulse filtering.
• Components developed in MX World Championship and in the USA, aimed at riders seeking durability and character.
• Stainless steel exhaust pipe for better longevity against heat and corrosion.

This exhaust line produces a competition-style sound and transforms the acoustic behavior of the DR‑Z, without guarantees of quantified performance. Note: track use only — not road legal and not noise approved. Before installation, check compatibility with your model and comply with local regulations.

• Main compatibility: SUZUKI DR‑Z 400 SM (2016, 2017) and DR‑Z 400 S (2014).

For riders who want to give their DR‑Z a race look, a refined finish, and a pronounced sound on the track, the Yoshimura RS‑4 remains a proven reference in the world of competition exhausts.
