I have a 2006 lbz duramax and i put a sinister diesel egr delete kit in it. it was fine for about the first 3 months then the pipe that comes from the manifold to the turbo and Ys off to the egr cracked. i replaced the pipe 1000$ later and it was fine for about another 2 months and now i have another cracked pipe and i was wondering if it is because i took my egr out and if it is this how do i fix the problem?

Just cut the bellow off and weld it shut. Or buy a lb7 up-pipe.

I actually did buy a lb7 up-pipe a week ago and im going to put that in from what i was told it should fix the problem. I just dont understand why it is cracking the Y pipe.

vibration and they are just known to crack, this is why we generally dont push the sinister kits. I always suggest the LB7 up pipe

X2, go with the LB7 uppipe or just cut/weld it shut. Youll keep cracking the bellow.
