I got these headers with a predator stage 3 kit,,it has changed the whole tone and throttle on my H2 SUT. no doubt there's increases bottom, top, mid..the sound is really cool as well..LS growl..i recommend for sure..

The Gibson headers are great. I put them on my 2004 Silverado 5.3L. The reduction in acceleration lag is great. I have an cold air intake, exhaust and power programmer to go along with the headers. I can feel the difference in acceleration and the low end torque. I would recommend them.

These were used as direct replacement for stock exhaust manifold replacement, sound is just a little deeper but nothing crazy
