We have over 7,000 miles on ours with no problems, but we have been running our own similar constructed gaskets on turbo cars for 7 years now with absolutely no problems.

We have never seen one of these multilayer gaskets fail even on cars that have been missing a down pipe bolt or, where other gaskets would have failed these have never let us down.

Also just for reference we use this style on manifold to turbo exhaust housings, gaskets in this application are exposed to tremendous heat not to mention higher pressures than any "post turbo" or NA exhaust pressure should ever be so even though we don't have 100,000 miles on them yet I have a lot of faith in them.
