Just to throw another datapoint out there, I’ve got stock headers and cats (no secondary’s) and the Corsa X-pipe and NPP. I got to meet up with RobZL1 and compare. His setup definitely was not as loud as I thought it would be. I would say maybe past 4 or 5k it has a little more volume than stock. My setup is definitely louder all around. Of course, I could be going deaf too
