i figured thats what it is. if i develop this problem i will probably go to AGA it looks like its alot more reliable and sturdy, URO uses alot of o rings as u mentioned and IMO looks kinda thin an flimsy, OEM well idk if theyre doing this already i would rather try an aftermarket solution rather than create the same problem again, i never looked into bimmer pipe but im sure theyre all better than stock design.
