MagnaFlow Redpack 3.5 in. x 12 in. 圓形玻璃纖維高效能排氣消音器 中心/中心

That deep, old-school tone came through the first time I started the truck. The 3.5-inch round body fits perfectly in the space I had, and it definitely gave the exhaust a richer note.

The deep tone this puts out is exactly what I was after, and the 3.5-inch round body fits perfectly in my truck's exhaust path. The classic glasspack sound is aggressive without being obnoxious on the highway.

Bolted this on in about twenty minutes and the 3.5-inch shell fits perfectly under the frame. The deep glasspack tone is unmistakable even at low rpm, and it doesn’t drone on the highway like I worried it would.
