MagnaFlow 4 英吋 x 18 英吋 圓形直通式性能排氣消音器 10424

Installed this on my Mustang GT last weekend, and the 4-inch round straight-through design really opens up the exhaust note without adding a ton of weight. The sound is deep and aggressive at WOT, but it's surprisingly tame cruising on the highway. Definitely delivers that dyno-proven performance I

Swapped this 4x18 straight-through onto my truck and the sound completely changed, deep and throaty without droning on the highway. The round body fit the space under there way easier than the stock can.

The 4-inch round case fit snugly into the stock location on my S10, and the straight-through design gives it a deep tone without being obnoxious inside the cab. Just wish the included clamps were stainless steel so they'd match the muffler's finish better.
