MagnaFlow Redpack 3.5吋 x 12吋圓形Glasspack性能排氣消音器 13115

That deep, rumbling idle is exactly what I was hoping for—my truck sounds meaner now. The 3.5-inch diameter fits perfectly in the stock location, and the build quality felt solid right out of the box. Only had it on for a week, but the sound hasn't gotten annoying yet.

Installed this on my ’87 Chevy and got that old-school, deep rumble I was after. The 12-inch length fit perfectly without any modification, and it’s held up well through a few hundred miles already.

The 3.5-inch core really woke up my truck’s exhaust note, and the classic glasspack sound is just right—not too raspy on the highway. Bolted on easily and the round body tucks under the frame without any clearance issues.
