Previously installed a Gibson cat-back exhaust system , there was a noticeable sound and performance gain.Just installed a set of Gibson shorty headers , power is more linear but does not seem to have increased performance much. But both are a high quality product , fitment was great and installation was reasonably straight forward.

When talking performance i will tell you these headers are awesome. After install which wasn't super fast for me they definitively did my truck good. I noticed increased gas mileage and throw me in my seat increase in power. Awesome product and lifetime warranty:)
