Description
Performance Muffler. The Flowmaster 70 Series Big Block II Dual In/Dual Out Oval Muffler; 2.25-Inch Inlet/2.25-Inch Outlet is designed to improve horsepower, torque, and engine efficiency while delivering a mild exhaust tone. It is ideal for trucks, SUVs, motorhomes, tow vehicles, and high-performance street cars, offering enhanced sound control and power gains for vehicles where space permits.
Construction and Appearance. Constructed from 16 gauge aluminized steel, this muffler features a robust build with full MIG welding for maximum durability. Finished with high-temperature paint, it boasts a black exterior that resists heat and corrosion, ensuring longevity and a premium look.
Installation. Installation requires moderate mechanical skill and may necessitate adapters for OEM exhaust connections since this is a universal muffler and not a direct fit. No drilling is typically needed, but new hangers are required as they are not included.
Warranty. This muffler is backed by a manufacturer’s warranty covering defects under normal usage.
Application. Designed as a universal fit muffler, it requires some adaptation for installation and is suitable for multiple vehicle types without direct fit guarantees.
