MagnaFlow Street Series キャットバック パフォーマンス エキゾースト システム 19377

The install was straightforward with hand tools, and the black coated tips give the rear a clean, aggressive look. Inside the cabin, it’s quiet at cruising speeds but wakes up nicely when you step on it.

That low grumble at idle is exactly what I was hoping for, and the sound is noticeable but not obnoxious inside the cabin while cruising. The dyno-proven power gain was noticeable on the highway too, though I didn't measure it myself. Very pleased with the upgrade.

The black coated tips look sharp against my truck's rear bumper, and the sound is deep without being obnoxious inside the cab. The dyno-proven power gain was noticeable during my first highway merge.
