Likely to be the only legal after market full system exhaust for the Suzuki DRZ400SM, the Delta Barrel 4-S Silencer is specially designed for street, enduro or super motard use. With a sleek and stylish appearance, its mid pipe is made of stainless steel while the body is crafted from lightweight hairline finish aluminium. It also comes with a FIM approved aluminum die-cast end cap.
With an improved emission efficiency and exhaust pressure, the Delta Barrel 4-S Silencer provides high power in the entire power band. Equipped with a special inner silencer body, its multi-stage expanding mid pipe design provides power on the high end, and rich torque at both the middle and bottom bands. Using only the best restrictor specific for each model, the exhaust gas circulation is smooth while increasing horse power and is definitely one of the top performing after market full system exhausts available in the market.
