Product Details

What you get with this MagnaFlow muffler is a well-built, straight-through design that's ready to give your exhaust system a healthy sound and improved flow. It features a 2.5-inch offset inlet and a 2.5-inch offset outlet, with a 5x11 inch oval body that measures 22 inches long. This muffler is designed to be bi-directional, meaning you can install it in either direction to fit your specific exhaust setup.

The core of this muffler is a perforated stainless steel tube that lets exhaust gases flow freely, wrapped in stainless steel mesh and acoustic fiber fill. This construction is key to achieving that smooth, deep tone MagnaFlow is known for, without creating excessive backpressure. Because it's made entirely of stainless steel, you can expect it to resist corrosion and hold up well over time. The satin finish on the body also adds a nice touch to your exhaust system's appearance.

While this muffler is universal, professional installation is recommended to ensure it's properly integrated into your exhaust system. It's a solid option if you're looking to change the sound and performance of your vehicle's exhaust.
