Re: Chev Colorado Cat's
The pipe must not be being allowed to move enough. If the system is too tight, meaning the hangers don't give the pipe any allowance to move with the frame of the truck as it twists down the road, the pipe has to give up somewhere, and probably at one of the connecting points. It will find the path of least resistance, and break there...

Looking at my new Cat it is much smaller and the header to cat is now a z shape the original one was just past the header connection and big. If you have the original one you might check for the weld braking loose over time/miles. If it happnes to many of these they may recall the original ones as mine is now the new desigin I'm set
