MagnaFlow 12469 universal performance muffler features twin 76mm (3") inlets and twin 76mm (3") outlets with an internal crossover design, making it ideal for high-flow dual exhaust systems where exhaust balance, compact packaging and effective sound control are required.
Manufactured from 100% stainless steel, the 12469 combines straight-through perforated cores with acoustic packing inside a large 127mm x 202mm x 450mm (5" x 8" x 18") oval body. The design allows both sides of a dual exhaust system to pass through a single muffler assembly while producing MagnaFlow's characteristic smooth, deep performance exhaust note.

MagnaFlow 12469 straight-through performance muffler is designed for high-flow dual exhaust systems requiring twin 76mm (3") inlets and twin 76mm (3") outlets. Its internal crossover configuration allows interaction between the two exhaust paths while combining dual-system sound control into one compact muffler assembly.
The large 127mm x 202mm x 450mm (5" x 8" x 18") oval body provides substantial internal volume for acoustic packing while the perforated straight-through cores maintain excellent exhaust flow. This combination provides effective sound control while retaining the smooth, deep performance exhaust tone MagnaFlow is known for.
The twin straight-through perforated cores provide a high-flow exhaust path with minimal unnecessary restriction, while the internal crossover allows interaction between the two sides of a dual exhaust system.
The large 18" oval body provides substantial acoustic packing volume to control exhaust sound while retaining a deep performance exhaust note. Final exhaust sound and volume will vary depending on engine capacity, engine modifications, catalytic converters, resonators, exhaust pipe diameter and the remainder of the exhaust system.
