MagnaFlow Redpack 4×26インチ ラウンド グラスパック パフォーマンス エキゾースト マフラー 13146

Installed this on my truck last weekend and the deep tone at idle is exactly what I was hoping for. The 4-inch diameter gives it a nice, mellow rumble without being obnoxious on the highway. It was a straightforward swap and the classic glasspack construction feels solid.

Dropped this on my old Mustang and the dyno-proven performance was immediately noticeable—made a big difference on the highway. The 4-inch round body fits perfectly under the chassis without any clearance issues.

That deep, throaty rumble at startup is exactly what I was hoping for. The build quality is solid, and you can feel the dyno-proven performance when you hit the gas.
