MagnaFlow XL系列 4吋x9吋x18吋 橢圓形多腔室性能排氣消音器 13264

The perforated tubing inside this muffler made a noticeable difference—my truck's drone at highway speeds is almost completely gone. It bolted up easily and gives a deep, mellow tone without being obnoxious. Very happy with how it improved the sound and flow.

The reflection design really cleaned up the drone on my truck, and the baffles give it a mellow tone that's not obnoxious on the highway. Installation was straightforward with the included hardware.

Bolted this onto my 5.3L and the idle drone I was getting with my old muffler is completely gone. The perforated tubing and baffle combo really opens up the exhaust note without being obnoxious on the highway.
