Xtreme Performance Exhaust 5 inch round performance mufflers are designed to deliver strong exhaust flow and an aggressive performance tone while maintaining better sound control for street and performance applications. Built with a straight-through louvered core and internal sound absorbing packing, these mufflers provide a deep, powerful exhaust note with a smoother tone compared to unrestricted race mufflers. The louvered core design helps improve exhaust flow and throttle response while still reducing harsh resonance and excessive rasp. Constructed from high quality stainless steel, these mufflers offer excellent resistance to heat, rust, and corrosion for long lasting durability in demanding driving conditions. The compact 5 inch round body with a 10.5 inch body length provides an excellent balance of sound, flow, and fitment flexibility for a wide range of custom exhaust systems. Ideal for muscle cars, trucks, hot rods, street performance vehicles, and custom fabrication projects, Xtreme Performance Exhaust mufflers are built for enthusiasts looking for a deep aggressive tone with reliable stainless steel construction and high flow performance. Designed for universal weld on installation, they are perfect for performance upgrades and custom exhaust builds where both sound quality and durability matter.
