Tim, I cannot give a comparison but I can tell you the Maxspeed headers are very well made and are a perfect fit. I definately could tell the difference in HP after installing them. They do have two O2 bungs which is why I bought them. I only had one CEL in 1,500 miles of driving. If I got another CEL I was going to try an extender on the rear sensor to move it out of the airflow.
