MWA 3.0in Center/2.5in D ual Oval Muffler

The Gibson Exhaust MWA 3.0in Center/2.5in Dual Oval Muffler is a universal-fit performance exhaust component engineered for vehicles requiring efficient noise suppression without compromising airflow. Designed for drivers seeking a balance between sound reduction and exhaust scavenging, this muffler serves as a drop-in replacement or upgrade for stock systems on a wide range of domestic and import platforms. Its dual 2.5-inch outlet configuration allows builders and enthusiasts to customize exit positioning while maintaining resonance control through a proven oval chamber design.

Built from stainless steel with a natural finish, the MWA muffler features an oval body measuring 14 x 9 x 4 inches with a 20-inch overall length and 3-inch center inlet. The oval cross-section geometry minimizes internal turbulence and heat buildup compared to round chambers, improving thermal efficiency and durability in high-temperature exhaust environments. The dual 2.5-inch outlets provide flexible routing options and accommodate performance systems where increased exit diameter is preferred, reducing back-pressure while maintaining acoustic tuning through internal baffle chambers.

This muffler is ideal for street-driven vehicles, custom exhaust builds, and restoration projects where OEM muffler packaging constraints exist. Universal fitment means welding or clamp-based installation is typical; verify inlet/outlet diameters and vehicle clearance before ordering. Weighing 12.06 lbs, it installs without adding excessive heat mass to the chassis. The stainless steel construction resists corrosion and scale buildup, making it suitable for all-season driving and wet climates where longevity is a priority.
