Yoshimura Signature RS-4 Dual Stainless Full Exhaust with Aluminum Mufflers | Suzuki DR-Z400S / DR-Z400SM 2000-2024

The Yoshimura Signature RS-4 Dual Stainless Full Exhaust System is a complete twin-muffler exhaust for the 2000-2024 Suzuki DR-Z400S and DR-Z400SM, built around a stainless steel header and Y-pipe feeding two pentagonal aluminum RS-4 mufflers with carbon fiber cone end caps — and it ships with a custom Yoshimura kick-stand.

The DR-Z400 has been in production essentially unchanged for over two decades, which is why one part number covers a twenty-four-year span and why the aftermarket for it is so deep. Its stock exhaust is heavy and restrictive, and the twin-canister RS-4 layout is the signature look for a built DR-Z, whether set up as a dual sport or a supermoto.

The included kick-stand is not a throwaway detail. The dual system changes the clearance around the stock stand, so Yoshimura supplies a replacement rather than leaving the owner to work it out — the kind of thing that separates a properly developed system from a generic one.

• Complete header-back dual exhaust system
• Stainless steel header and Y-pipe with twin aluminum RS-4 mufflers

Fits the 2000-2024 Suzuki DR-Z400S and DR-Z400SM as a direct replacement for the complete stock exhaust, and is the definitive full system for DR-Z400 dual sport and supermoto builds. Fit an approved spark arrester insert before riding on US Forest Service or BLM land.
