LeoVince - LV-X Slip-On Muffler - Suzuki DR-Z4S

The 2025+ Suzuki DR-Z4S introduces a long-awaited modernization to a legendary platform, but it arrives hampered by a heavy, highly restrictive factory exhaust system designed to meet stringent global emissions standards. The LeoVince LV-X Slip-On muffler offers an immediate solution, allowing the new fuel-injected powerplant to breathe freely while significantly reducing overall vehicle weight.

Designed specifically for the updated DR-Z chassis, the LV-X features a high-resistance aluminum sleeve paired with a semi-direct internal chamber. This configuration is engineered to optimize exhaust velocity and improve mid-range torque without requiring invasive engine modifications. Weighing in at just 4.43 kg (9.76 lbs), this slip-on eliminates 1.55 kg (3.4 lbs) of bulk high up on the subframe, resulting in a noticeably more agile feel on the trail.

Features:

• Lightweight Construction: The high-resistance aluminum sleeve and minimized internal components save 1.55 kg (3.4 lbs) compared to the factory Suzuki muffler.

• Semi-Direct Chamber: The internal acoustic design improves exhaust scavenging and throttle response while delivering a deep, aggressive exhaust note.

• Carbon Fiber Fastening Strap: Secures the muffler to the subframe using a full carbon fiber clamp, eliminating the weight and heat transfer of a traditional steel bracket.

• Adjustable Acoustics: Includes a removable dB-killer, allowing riders to configure the sound output from a trail-friendly 87 dB(A) up to an aggressive 98 dB(A) at 4000 rpm.

• Premium Finish: Features a durable, brushed aluminum exterior completed with a precision laser-etched LeoVince logo that will not burn or peel over time.
