MagnaFlow XLシリーズ 4×9×18インチ オーバルマルチチャンバーパフォーマンスエキゾーストマフラー オフセット/オフセット

Installed this on my F-150 and the offset/offset fit perfectly with no modifications needed. The perforated tubing inside really opens up the exhaust note without being obnoxious at highway speeds.

The baffle design really tames the drone on the highway without choking the flow—my truck feels noticeably more responsive in the mid-range. I was also surprised how easy it was to swap out the old unit, given the offset/offset ports. This thing’s a keeper.

The offset/offset layout lined up perfectly with my factory hangers, so the install took under an hour. The multi-chamber design killed that annoying drone at highway speeds while still letting the exhaust breathe noticeably better.
