Description
Performance Muffler. The Flowmaster 40 Series Delta Flow Center/Center Oval Muffler with 3-inch inlet and 3-inch outlet is engineered to improve exhaust flow using chambered Delta Flow technology. It produces an aggressive sound well-suited for street, strip, and off-road use, effectively reducing interior resonance while enhancing scavenging for improved engine performance.
Construction and Appearance. Constructed from durable 16 gauge aluminized steel with full MIG welding, this muffler offers long-lasting strength and durability. It is coated with high-temperature black paint that provides corrosion resistance and a sleek, professional look compatible with many vehicle styles.
Installation. Installation is made easy with slip-fit inlet and outlet connections that support clamp-on or weld-on mounting methods. This muffler requires the use of new hangers, which are not included, and typically does not require additional drilling for mounting.
Warranty. The product is backed by a limited warranty against defects in materials and workmanship.
Application. Designed for universal fitment, some adaptation may be necessary depending on specific vehicle configurations and exhaust systems.
