Hey guys, how's it going? I recently purchased an 01 GT (auto) with 4.10 gears, flowmasters, BBK cai, and an sct livewire. OK, so on to my question. When I accelerate to speeds exceeding 85, my car gets really unstable. It feels as if I could lose control very easily. There's a lot of noise and shaking. My steering wheel also feels loose (idk if this is related at all, may be normal?). I just had it inspected, got new tires (was doing it before the tires as well). I just don't know what it could be, but I'm sure some of you will have some idea. Thanks a lot guys.
