Product Description

The Magnaflow 12267 universal performance muffler is engineered to enhance exhaust flow while delivering the deep, smooth tone that Magnaflow is known for. Its large 18" x 5" x 8" stainless steel oval body houses a straight-through perforated core that promotes efficient exhaust flow and reduces backpressure compared to many restrictive OEM mufflers.

Featuring a stepped inlet/outlet configuration - 3" inlet to 2.5" outlet - this muffler integrates into performance and custom exhaust systems where a transition from larger to smaller diameter piping is desired. The durable stainless steel construction provides excellent corrosion and heat resistance for long-lasting performance. The reversible, bi-directional design allows flexible installation orientation for various custom layouts. Ideal for performance builds, custom exhaust systems, or replacement applications where improved flow and Magnaflow's signature tone are desired, this universal muffler requires professional installation (weld-on or clamp-on) for proper integration and performance.
