Product Description

The Magnaflow 12198 universal performance muffler is engineered to enhance exhaust flow while delivering the deep, smooth tone that Magnaflow is known for. Featuring a large 16″ × 6″ × 10″ stainless steel body and a straight‑through perforated core, this muffler minimizes backpressure and improves exhaust dynamics compared to many restrictive stock units. Its robust construction is designed to withstand heat and corrosion, making it a durable choice for performance and custom exhaust systems.

With 3″ inlet and outlet diameters, the 12198 integrates cleanly with common exhaust piping sizes used in performance builds and replacement applications. The reversible and bi‑directional design allows flexible installation orientation, accommodating a range of custom layouts. Ideal for enthusiasts building or upgrading custom exhaust systems, this muffler requires professional installation (welding or clamp‑on) to ensure proper integration and performance.
