I took off the plates he was using to block cutouts that SRTPowa put on this XF and my god... took it out on the town to hang out with the "race kids" i like to call them and even they sayed i was way to loud. I came home at around 3am and was hardly above 2k rpm and it sounded like i was gunning it.. i had to role up the windows to help a lil but even that deep growl was loud as hell and vibrated everything in the car.. I had to put the plates back on but cant wait to get the electric cutout's working its going to be very nice to have on demand but all the time.. noooo wayyy
