At DMG Motorsports, we present the Yoshimura RS-4 Full Exhaust System (SS-SS-CF, part number 146500D520) - a race-bred, full-system upgrade engineered to deliver an unmistakable exhaust note along with real performance gains. Built around Yoshimura's proven RS-4 platform, this system pairs a durable stainless steel header and mid-pipe with a stainless steel muffler and a sharp-looking carbon fiber end cap, giving your bike a lighter, more aggressive stance without sacrificing durability. Whether you're chasing lap times or just want your ride to sound as good as it performs, this full system is designed to bolt on and deliver results right out of the box.

The heart of the RS-4 is its pentagonal-shaped muffler with maximized internal volume, working alongside a polyresonant duplex front chamber and a stepped, two-stage core baffle to tune the exhaust note while helping optimize power delivery throughout the rev range. Yoshimura's engineering pedigree comes from decades of championship-winning race development, and that same R&D has been channeled into this current-generation RS-4 to provide an unrivaled combination of power and a refined, quiet exhaust tone. The system is also spark arrestor/sound insert compatible, giving riders flexibility for track days, trail riding, or street use.
