Hey guys, I was wondering what the best way to make my exhaust louder would be. I am currently running stock headers, Bassani catted x, and Borla Stingers. I wanted to go with a Bassani off-road x pipe but to my knowledge I would have to re-tune the car which I am really not trying to do. So I was thinking Borla ataks, would that be the better and cheaper alternative to get the car louder? Or could you just run the x-pipe without a tune? What would you guys recommend? Thanks!
