MagnaFlow 3.5インチ x 7インチ x 14インチ オーバル 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 11134

Swapped out the stock muffler on my truck and the deep tone at idle is exactly what I was hoping for, no drone on the highway either. Fit perfectly in the factory hangers and the 3.5-inch oval body looks clean underneath.

Installed this on my Mustang GT and the sound is perfect—deep and aggressive without being obnoxious on the highway. The 3.5-inch oval body fits easily in the stock location, and I definitely feel a seat-of-the-pants difference in throttle response.

The oval shape fits perfectly in my tight chassis, and the sound is deep without being obnoxious on the highway. I’ve already felt a noticeable improvement in throttle response during acceleration.
