Hi fellow 981 owners, looking for some exhaust help here. I currently have the PSE hooked up to Cargraphic headers on my Boxster S, and it drones pretty bad in both 6th and 7th gear between 2000 and 2800 rpm. I am wondering if anyone has upgraded to a different exhaust from the PSE? What exhaust did you end up with and did it help with the drone? Also, can someone help with a list of 981 exhausts that can make use of the PSE button in the car? Thanks!
