Should have listened to my elders....this is why after you unbox you jba headers, the second thing you do after inspecting you headers is throw away your supplied gaskets...

Failure after 1k miles

It's not just JBA gaskets that do that. For really challenging joints where the flanges don't mate up well I've been using Remflex gasket material.

Yea. I had an issue with oem b pipes not mating since the flange isn't the sealing surface, the crush donut is the sealing joint. I used the gasket material goo, but it heated up and pushed out over time...not much time either. I couldn't believe how not flat the oem b pipe flanges are.

The two bolt design isn't the greatest thing in the world. Careful use of a file and/or flap disc can greatly increase your chances of getting a good seal. You can also weaken the flange ears if you don't have at least 3/8 inch flanges.
Using anything other than a metal gasket increases your chance of bending the flange ears, which will cause a blowout.

That sucks! Only on 1k miles and you are out? It is always recommended to have some spares especially when you are trying a new brand. Also, always go with the brand that you completely trust or has only had positive reviews throughout its whole existence in the market.

All,

I ran out of the OEM ones, and used the JBA in a pinch. Yes, I understand JBA gaskets would fail, it was only on 1 B-pipe joint. Yes, I understand the OEM ones are reusable, and use them when I have them around. I have all OEM, and some doubled up on all other b-pipe joints and as of now, do not have any leaks. I used the JBA gaskets in a pinch, since Amazon lead time for OEM gaskets as of lately has been almost two weeks. Header to manifold gaskets, I didn't take any chances and installed new OEM gaskets, not problems to report yet.
