1 year old Wes, I went back to Scott at AAPerformance Muffler and they checked out fine. Working hard but as good as the day installed. Scott said my EGR tube was probably gunked up so I pulled that and it's clean. I had a flat spot on acceleration which was fixed by the tune-up and the trucks running better but the NOx is increasing.
