Standard replacement for my 5.7 liter GMC Vandura Explorer van. At 93, the standard system was absolutely silent. This muffler added some hum to the new Magnaflow 94009 Cat. Now I can hear my engine's exhaust sound, but not too much.
Old muffler has rusted. I was able to remove the old muffler and exhaust pipe and install this new muffler. I needed a tool/angle grinder to cut through the existing clamps and clean up some connection points. I also bought a new exhaust pipe. Van is quiet and works well. Plug and play / work. Doing it yourself saved a lot of money back then. A few years later I'm still happy with the product and how it's holding up.
