Description
Performance Exhaust Solution. The Flowmaster 70 Series Big Block II Offset/Center Oval Muffler; 2.50-Inch Inlet/2.50-Inch Outlet delivers a mild exterior exhaust tone with minimal interior resonance, designed for trucks, SUVs, motorhomes, and high-performance street vehicles where space permits. It enhances horsepower, torque, and engine efficiency while providing improved sound control with Delta Flow® technology.
_x000D__x000D_Construction and Appearance. Constructed from 16-gauge aluminized steel, this muffler features a large oval body with a high-temperature black paint finish for durability and corrosion resistance. Each unit is fully MIG welded to ensure strength and long-lasting performance under rigorous driving conditions.
_x000D__x000D_Installation. This muffler employs slip-fit inlet and outlet connections with an offset inlet and center outlet location, compatible with clamp-on or weld-on installation methods. It requires new hangers, which are not included, making adaptation necessary and professional installation recommended.
_x000D__x000D_Application. Designed with universal fitment in mind, this muffler requires some adaptation for proper installation and is not a direct fit for specific vehicle models without modifications.
