So I recently noticed this noise, I have all stock exhaust except for cajun resonated bpipes. My tuck sounds exactly like the one in this youtube video that I will link. I have long tube headers but I am waiting to put them on until can afford the tune. I have read horror storries of cat material getting sucked up into the engine. Just wondering what you all think? The noise happens at 2k rpm and startup

Do you have a check engine light? The light will indicate a failing cat and thats when you could have issues.

No light on, but very annoying hopefully its a heatshield or something I guess
