They definitely do what they intend to do, free up the airflow. Very easy to install, they bolt right in. Look out for broken manifold bolts on your vehicle. I ceramic baked mine at home, the tube gauge is thinner than what I expected for the price. Messy welds, and messy detail on the inside of the exhaust flange where it mates with the tube. Definitely helped with the sound of the exhaust and freed about 10-15 horses in my set up (no dyno).
