MagnaFlow 4 吋 x 18 吋圓形直通性能排氣消音器 中心/中心

The sound is deep and aggressive without being obnoxious on the highway, and the weight savings over my old chambered muffler were immediately noticeable. It's also a perfect 18-inch fit for my truck's short wheelbase.

The install was straightforward, and once I fired it up, that deep, throaty tone was exactly what I was after. It shaved off a few pounds compared to my old muffler, and the 4-inch round body fits perfectly under the chassis.

The weight difference was the first thing I noticed when I lifted it out of the box—it’s noticeably lighter than the stock unit, which made the install a breeze. Once it was bolted up, the straight-through design gives a deep, aggressive tone without any annoying drone on the highway.
