Product Description

The Magnaflow 12589 universal performance muffler is engineered to improve exhaust flow and deliver the deep, smooth tone Magnaflow is known for. Featuring a large 22" x 5" x 11" stainless steel oval body and a straight-through perforated core, this muffler helps reduce backpressure and enhance exhaust dynamics compared to many restrictive factory units. Its robust stainless construction provides excellent resistance to corrosion and heat for long-lasting performance.

Designed with a 3" center-to-center inlet and outlet, the 12589 integrates easily into performance and custom exhaust systems using compatible piping. The reversible, bi-directional design allows flexible installation orientation to suit a variety of custom layouts. Ideal for custom exhaust builds, performance upgrades, or replacing restrictive OEM mufflers, this universal unit requires professional installation (weld-on or clamp-on) to ensure proper integration and optimal results.
