MagnaFlow XL 시리즈 4 x 9 x 14인치 타원형 멀티 챔버 퍼포먼스 배기 머플러 13148

The perforated tubing really smooths out the highway drone without killing the rumble, and the multi-chamber design makes it sound deeper than I expected for the size. Bolted right up to the stock hangers, no extra welding needed.

Swapped out my stock muffler for this oval multi-chamber design and the difference in sound is night and day—deep tone without being obnoxiously loud on the highway. The reversible reflection style really cuts down on that annoying drone I used to get at cruising speeds.

Installed it on my F-150 and the drone on the highway is way down compared to my old straight-through muffler. The perforated tubing and baffle design really does help keep the cabin quieter while still letting the V8 breathe. Only downside is it’s a bit heavier than I expected for the size.
