So, I installed my system a few months ago, and I have some minor issues.
Let me prefice this by saying I absolutely LOVE the look, and sound of the system I chose. HOWEVER, I am experiencing a lot of secondary noise that literally makes the car sound like garbage.

Under moderate/heavy acceleration I am getting the common rattle in the rear area that sounds like its coming from the spare tire section ( which is annoying but not bad by itself). I am also now experiencing a quick more noticable and loud rattle in between 3000 and 3500 RPM's that almost sounds like a BB in a coke can vigorously shaking, which sounds like it's coming from right under where the headers would be. Also the all too infmaous VQ Hiss, for me, now isnt just on decel, but also heavy accel from 3 - 6000 RPM's ( ??Exhaust Leak?? ).

All things considered, as much as it kills me, I am thinking about removing the system and going back to stock. Before I do so, I think I may take it to a shop to have it looked at to see if something wasn't done correctly on install. All of these secondary noises are seriously driving me insane! Anyone have any ideas here? Or similar occurences?
