Overview
The MagnaFlow 12589 is a satin stainless steel muffler with a 3-inch offset inlet, a centered outlet and 3-inch inlet and outlet tubes. It is a straight-through muffler suited to universal fit applications, with no vehicle named.
MagnaFlow builds it from 100% stainless steel with lap-joint welds, then adds a perforated straight-through core, stainless mesh wrap and dense acoustical fiber fill. The fill is there for a smooth, deep tone, and the muffler carries a Lifetime Warranty. The offset inlet and 3-inch tube size need to match your exhaust before it is fitted.

Tone and sound level
Sound comes from more than the muffler alone. Tube size, the engine, the rest of the exhaust and the packing all shape the note. A dense acoustical fill generally produces a deeper, smoother tone than a bare shell, but it does not turn a restrictive system into a quiet one. If the tone changes sharply after a repair, check that the pipes and joints are sealed.
Choosing a muffler is easier when the tone goal is clear. Someone who wants a steady, lower note will usually look for a fuller core, while someone chasing a louder sound may need different packing. Local noise rules also apply, so check them before fitting an aggressive setup.
- Match tube size to the existing pipe
- Seal joints before judging the sound
- Check local noise rules
