Exhaust flex coupler for turbo build
I'm guessing lifespan depends a bit on the usage. For a guy who cruises around, never really runs a bunch of boost or stay in boost long, doesn't have high backpressure, and doesn't use a two step often it may last a lot longer. In the instance of my failure I had a maxed out turbo with high backpressure, lots of pops and bangs, and beat on all the time and it lasted a few months. In another example I saw one blow completely apart while on the two step on a 5.3L with a larger turbo, we literally put beer cans around it to finish the event so it didnt torch the engine bay. 
Even the bellows posted above backpressure has made them expand and those are a good bit stiffer than the braided joints but at least with overlapping pipes inside they don't typically blow out or send pieces into the turbo. So now I prefer solid mounting if I can, haven't had any issues with that.

I used flex couplers from Columbia Mandrel bends. Bellows on the inside, braid on the outside. As was shown to fail in a prev post.
Been on the car since 2013.
my turbo is solid mounted to the frame. So I needed to use them.
They aren’t set up in any sort of radial twist.
This post got me curious. I have the hot side off for engine removal, so I poked the bore scope in there to look.
Still perfect.
Happy to see that

Do a search for Marman Clamp. They were originally designed as a coupler for holding bombs.
