Im not running it nor do i have a video but i can tell you its going to be crazy loud. The atak is one of the loudest cat backs on the market todate. You are def going to be turning heads. Go with some high flow cats and a atak cat back, its still will be loud as f***.
got borla ataks with stock hpipe and it seems decently loud with all 4 cats. im going to be buying a catted x once they are in stock. on the 03/04s it seems way to loud wtihout cats.
