ok, so heres my deal.. and yes i searched, found a few things that might be useful but not entirely sure... i have a weird sounds that sounds like two pieces are grinding/vibrating together mostly around 3500-5k rpms. or even sounds like if my exhaust pipe split and started hitting itself.. since im at school, i dont have a place to work on my car or a lift to check. Heres what i think. i either have a crack in my exhaust (which would suck major ass), an exhaust bolt could have gotten lose cuzing the tubing to vibrate, or when minike put my resonator on a weld could have split. i can only here the noise when im in my car and its on the pass side where my exhaust runs or could be near my engine bay. My cel light has been on for awhile, never relocated the O2 sensor cuz i need a lift since my entire exhaust is welded and my mechanic didn't feel confortable to mess with the O2 sensor, didn't want to mess things up. any suggestions or useful threads discussed on this that i might have missed
