About this part

Product Details

Magnaflow is well-known for making performance exhaust components. This muffler, part number 14153, is built for custom exhaust projects where you want a smooth, deep sound. It uses a straight-through perforated stainless steel core wrapped with acoustic fiber fill, all contained within a durable stainless steel body.

The construction here is solid. Magnaflow uses CNC robotic manufacturing for precision, and the entire muffler is made from 100% stainless steel, making it resistant to corrosion. It's also fully reversible, meaning you can install it in either direction, which can be helpful during custom fabrication. The 5x14x8 inch body and 4-inch center inlet/outlet make it a versatile choice for many applications.

This muffler is designed to give you a noticeable improvement in exhaust tone without being overly loud or raspy. It's a well-built piece that should hold up well over time, backed by Magnaflow's limited lifetime warranty.
