This is the absolte best exhaust I have ever heard!! The build quality is 10/10, and installation was a breeze. If you have any hesitation on buying this exhaust, don't! Just buy this exhaust, it'll be the best decision you'll make! ABSOLUTELY NO DRONE AT ALL!!! I bought the dual exhaust part number 24274 for a regular cab short best silverado 5.3L!
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.
