Installed my MBRP exhaust last after already having Injen CAI and Ark secondary downpipes installed earlier last week. Setup sounds great, but have an unbearable drone at highway speeds (70-80mph) at 2000-25000rpm in sport mode. Switching to comfort mode brings the rpms down to right below 2000 and the drone becomes somewhat tolerable. Have tips waiting to be shipped from aliexpress so hoping that will help the situation a little bit.
