They worst thing you can do is solid mount the turbo without any float, why do you think it kills the flex joint? That is weakest section of the run, it isolates the majority of the movement to that


The double slip is by far the superior joint for something like this when you cant put a Bellow/flex in the correct position like an OEM can

The double slip is simple and the strongest part of the whole hotside, it is 3 overlapping walls of the parent tube

Sure run the hotside without any flex and think it's super.... There is so much stress along the run through the heat cycles you will see how well that stands up long term

Take a 3ft long chunk of 304 stainless tube........ Increase the temperature 1000*f. ...... The pipe has grown in length over a half inch
built a turbo ls swapped 96 trans am in 2008... no flex in the crossover... it’s been through 5 owners and 12 years without a crack 🤷

mines been over a year with no slip or flex and I drive the car ALOT. It’s almost a daily. I can’t say it’s a daily because I sometimes drive my truck too, but I drove it to work yesterday and today. It’s been out of state on a road trip a couple times. I dunno. I think if I haven’t had a problem by now, it’s good.

I use a bell on one end so the other slides in, use a band clamp-makes it easier
to make up the crossover pipe. You realize car manfs. made crossover pipes for years
as one piece.

Good point. But the internet’s don’t care. They say it won’t work. And you gotta have a flex or slip joint. I’m not gonna tell my car that so it’ll be good as long as I don’t tell him what the internets says. Lol.
theres always some chemical mechanical science specialist engineer that has a nuclear triple degree in know it all ism that will tell you that you are doing it wrong. But yet it’s been working for many people for many years. Lmao.

That's because the engine grows too.
