I have a Roush Performance Cat-back exhaust. I love the way the truck sounds from outside the truck but inside the truck between 2000 rpm to 2500 rpm there is a drone in the truck that makes me want to stick a ice pick in my ear! Has anyone had any problems with interior noise being too loud with this exhaust and has anyone else had better luck with other brands I’m about to put the stick muffler back on and just keep the over axle Roush kit out the back. Thanks guys!
