I will try and get some video from the outside this weekend. When I first installed the GHL I was very disappointed with the amount of resonance I had. I even wrote them a letter complaining about it. I was constantly keeping the revs above 3K or below 2k. My wife hated to ride in the car.

I recently installed the Fabspeed Cat Bypass pipes and it changed for the better. The ear piercing resonance has diminished quite a bit. It can still be annoying between 2K-3K but it’s not nearly as bad. I love the sound now. It’s rawer and I think it’s what a Porsche should sound like. I even had the service guys at the dealership ask me if I had a Tubi exhaust on the car, which they sell.
