MagnaFlow Muffler Mag SS 18X5X8 2.5/2.25X2.25

Magnaflow is well-known for making exhaust components that sound great and perform well. This 18-inch long, 5-inch by 8-inch oval muffler, part number 12258, is a prime example of their approach. It uses a straight-through perforated stainless steel core, wrapped in mesh and acoustic fill, which helps it flow freely and produce that signature Magnaflow sound. This design is key to getting a smooth, deep tone without sacrificing too much performance.

The muffler body is made entirely of stainless steel, so you can expect it to hold up well against rust and corrosion over time. It's designed to be bi-directional, meaning you can install it in either direction, and it has a universal inlet and outlet setup that can accept either 2.5-inch or 2.25-inch piping. While it's a universal part, the 5x8x18 inch oval body is a common size that fits many applications, and its satin finish looks clean under your vehicle. Because this is a universal muffler, professional installation is recommended to ensure it's welded in correctly and securely.
