I have an aftermarket downpipe that was installed about a year ago. Within that year the studs have backed out on there own causing a massive gap 4 times. I have replaced the studs with brand new nuts and studs every single time. I have used red lock tight 3 times to no avail. I dont quite see the reason why they are backing out. But this last time they backed out it caused my entire turbo blanket to tear in half and start smoking which led to the front portion of my valve cover melted. Does anyone know of a way to correct this problem or why it may be happening.

 

Is it the stud backing out of the turbine housing, or the nut loosening on the stud?

 

The whole stud is backing out of the turbine housing. And it's not just one. All three studs are backing out.

 

There's a bracket that connects the downpipe to the block, are you using that bracket?
