Description

The MagnaFlow 6in. Round Straight-Through Performance Exhaust Muffler 12644 is a universal muffler designed for custom exhaust applications. It features a straight-through, free-flowing design with a 2-inch diameter inlet and outlet. The muffler's internal construction includes a perforated stainless steel core, stainless steel mesh, and acoustic fiber fill for a powerful, resonant tone.

Constructed from durable, corrosion-resistant stainless steel, this muffler is produced using CNC precision robotic manufacturing techniques and is backed by a limited lifetime construction warranty. Professional installation is highly recommended due to the cutting and welding involved.
