MagnaFlow 4 x 9 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 14316

I wasn't sure how much difference a muffler swap would make, but this straight-through design really woke up the throttle response on my truck. The perforated core gives it that deep exhaust note without being annoyingly loud at highway speeds.

The 4-inch oval body fit perfectly into the tight space under my car, and the stainless steel finish already looks great after a few days. It has that deep, mellow tone at idle but really sings when you get on the throttle.

Installed this on my truck last weekend and the sound is exactly what I was hoping for—deep and aggressive without being obnoxious on the highway. The straight-through design really wakes up the throttle response, and the welds look clean and solid.
