Overview
The MagnaFlow 10445 is a 14 in long, round satin stainless steel muffler with a straight-through flow path, centered 2.25 in inlet and outlet tubes, and one inlet and one outlet. MagnaFlow Exhaust builds it from 100% stainless steel with lap-joint welded construction.
The perforated stainless steel core runs straight through, and stainless mesh wrap and acoustical fiber fill are packed in. This build is intended to give a smooth, deep tone and long service life, and the acoustical fill helps keep sound from degrading over time. A Lifetime Warranty applies.
Confirm fit for your vehicle’s year, model and trim before ordering. Compare the 2.25 in inlet and outlet and the 14 in length with your current exhaust before buying.

Choosing a replacement muffler
A muffler quiets exhaust by routing gases through chambers and packing that absorb sound energy. A straight-through design like this one gives a direct flow path, which many owners choose for a more open, deeper tone. Less restriction can also shift the note toward a louder character, so consider how much noise you want before buying one.
Because a muffler is one part of a complete exhaust, check the pipe diameter, connection style and body position on your current system. Hangers, clamps and gaskets are often replaced at the same time to keep alignment and seal integrity. Inspect the flanges for rust before fitting the new unit, since a worn joint can leak exhaust toward the cabin area and cause a noticeable drone.
Stainless steel resists corrosion well, which matters in road salt climates where mufflers rust out from the inside. Confirm the mounting method and make sure the exhaust is supported after installation so the new muffler does not stress the pipes.
