I finally came around to putting it on, i have the mootiv overpipe, berk catted front pipe and ARK DTS catback. The vibrations are really harsh throughout the cabin, the whole car vibrates during idle and acceleration. It feels like i changed cam profiles more than i changed headers.

I had the exact same set up without headers and overpipe for a long time and did not have any issues with vibrations.

I think i'm rubbing somewhere, perhaps with the overpipe, but clearance seemed fine when we installed everything, i will doublecheck soon but i am curious if such vibrations are common with this header. All the plastics won't stop rattling.
I had the same problem when I installed this header a couple months ago with everything else stock. It was crazy noisy too. Turns out it was the head vibrating against the skid plate. I just had to bend the skid plate a little to make it bow down and fit without rubbing. Afterwards, it was as quiet as stock.

You may want to just pull the skid plate off and take a look around. If anything is rubbing, there will be some visible wear on both parts wherever it's happening.
