Not using the cat bracket on your exhaust will cause this.
The only guess i have is to why my exhaust keeps falling apart is that the cat bracket was not attached to it. This resonater that split is a Vibrant product, it is stainless steel. The megan test pipe i had on before this also split in exactly the same place as the vibrant one. Now is this just a problem with a 70$ resonater and a knockoff part, or is it not having the cat brace attached to it.

I ran no support on my test pipes and they cracked. I fixed them and put a brace back on the car to see if that would fix it they then broke again. the combination that i have now... few thousand miles... is a flex joint in each test pipe before the brace and the existing flex joints that are on the y pipe. The exhaust was too rigid before the addition of the second flex joints and that is what caused it to break. Good luck with the fix....they (exhausts) can be tricky to get right the first time.

Poor welding and design quality.

+1 vibrant stuff is made overseas and would have been machine welded. nothing wrong with that really, but when they polished the welds out, they knocked that area down really thin, hence bairily any thickness or filler material in the weld. thats why it made such a nearly perfect clean break.

*edit*
I dunno, the weld failed regardless

Ashmo yes i made the ypipe and the resonators one section of the exhaust. I bought these off of ebay from verocious motorsports. I contacted them about it breaking and sent them pictures. They contacted vibrant and they offered a refund or a new resonator. Vibrant said it is a manufacturing defect. Ill have a new section made in a few weeks, ive been thinking about a couple of ideas. I put my cats and stock Y pipe back on for now. It feels like i lost 20hp or more.
