Ark Grip V2 Scrapping issues?

Fearless_Z

Sounds something like if my trunk wasnt shut all the way, only when the car is under load and only when i hit a hard enough bump, sometimes. But its underneath my car. When it does it, i can feel it through my shift knob pretty hard when i have my hand on it. I already sent it to Nissan, we figured it was these bolts that were too long underneath this red stabilizer bar, it looked like that was the problem. So i got the bolts cut to where they wouldnt hit and i still keep getting this knocking sound as if something is just very loose. My Ark exhaust is very very stiff. So im really lost at what it could be.
