Quality headers above the rest! great fit the installation went smooth no issues. comes with all necessary hardware (headers bolts) stage 8. and gasket. about performance.. no doubt gains are notable going to dyno after retune. I recommend get Taylor sparkplug wires/cables 9 or 10 inch with 45 degree.
2014 Silverado 1500 High Country 6.2L V8
Installed this on my 2014 Silverado 1500 High Country 6.2L V8. Truck sounds amazing but the only downfall is the drone noise when it goes into V4 mode I am looking into getting the AFM Range so it disables V4 mode. When installing this system I ran into a problem with the catalytic converter clamp as it was all rusted and the threads came off I had to order a new clamp since corsa didn't provide one.
