Headers fit but wrong gasket.
The headers look and sound great. The technician could not install it at first because of the gaskets sent did not fit my 2012 RAM 1500. They had to modify a factory gasket to compensate for a sensor inside that had an odd shape not accounted for in the parts sent for these headers. Ended up costing me an extra 300$ for labor. Be sure they either send the right ones or you know exactly what the gasket should look like before you take to the install tech.
