So last week I had fast intentions rhfc and their catback with 18" res. In serve or more sound I added berks hfc last week. On Friday I had the dc headers installed. So last night I decide to install the aam air intake. Did drive because it was late. I woke up early this morning and re did My headlights. So I started driving and notice the car had serious vibrations that wasn't their when I picked it up from the shop on Friday. The whole car vibrates when I'm stopped in drive. I put it in neutral and the same thing. It's sounds super loud like I have a bad exhaust leak or something. Anyone ever experience this? Can the intakes cause this rattle vibration that is loud. It's actually louder in the car then it is if your outside the car. All help is appreciated to help me diagnose this
