wasn't really sure how they would sound with a 3.8L but I guess it is what it is its not some monster v8.But yes I Really do enjoy the deep sound, Ive ALWAYS loved the sound of FLOWMASTER.

Solid Muffler. Good Sound!

Reviewed By Nicholas O (Algonquin, IL) Reviewed for a 2000 Ford Ranger —4/19/2017 3:52 PM

Solid construction and good fit because.....its universal! Most of my exhaust is custom since the original rotted out so it sits only a foot off the cat pipe and turned down....if a good rumble is what your after this muffler will suffice but your scenario may differ.
