I began thinking this after work I am going to check I just need to find a second person hanging upside down out the door is kind of tough lol 😂 fingers crossed on placing a finger on the issue today im hoping it’s a cat it started up near motor which could be why I thought it was under valve cover but when I got home I’d it was the first cat it could’ve shook some of the honeycomb loose and tossed it to the second one just a theory if this is the case is there a way I can remove the piece inside without destroying exhaust until I find a low mile oem cat thinking of just buying an entire srt6 online and tearing it down for parts
