About this part

Product Details

This MagnaFlow muffler uses a straight-through, perforated stainless steel core. That design lets exhaust gases flow freely, which is key to getting that improved exhaust note and a bit more performance out of your engine. It's a universal muffler, so it can be installed in any orientation you need, with a 2.5-inch inlet and a 2.5-inch outlet that are both centered on the muffler body.

The muffler body itself is a 4-inch by 9-inch oval, measuring 18 inches long, and it's constructed entirely from stainless steel. This not only helps resist corrosion but also contributes to the muffler's deep, smooth tone. Inside, acoustic fiber fill works with the perforated core to manage the sound, giving you a healthy exhaust note without being overly loud or raspy. The satin finish on the stainless steel body also gives your exhaust system a cleaner look.

Because this is a universal part, professional installation is recommended to ensure it's welded in correctly and securely. It's a well-built option if you're looking to change up the sound of your exhaust and gain a little bit of flow.
