MagnaFlow 7インチ×20インチ ラウンド ストレートスルー パフォーマンスエキゾーストマフラー 12771

First fire up and the deep, mellow idle had me grinning — that signature sound is exactly what I wanted. Even at highway speeds, it settles into a smooth rumble without any drone.

The install was straightforward, and the 7-inch round body fits perfectly in the stock location. It gives a deep, mellow tone that’s not too loud, and the dyno-proven performance boost was noticeable on my truck.

The straight-through design really wakes up the throttle response on my truck, and the low rumble at idle is exactly what I was hoping for. Install was straightforward, and the build quality feels solid for the price.
