2007–2018 Jeep Wrangler JK Muffler Delete | Axle-Back Exhaust | 3.6L & 3.8L V6

It's noticeably louder than stock — that's the point. You get a deep V6 growl that wakes up under throttle and settles down at cruise. It's an axle-back delete, not a full straight-pipe, so it's aggressive without turning the cabin into a drum on the highway. If you want whisper-quiet, this isn't it. If you want your Jeep to sound like it means it, it is.
