Looking for sheets of exhaust gasket material I can buy off the counter at an Advanced Auto Parts, AutoZone, or Pepboys. Something that will obviously hold up to our EGT. No, I can't buy pre-made flange gaskets and prefer not to order because I need it ASAP.

All I've found are these:
Gasket Material | AutoZone.com

Advance Auto has a turd of a website, so I can't link the gaskets by FelPro and Mr. Gasket I've found.

 

Have you tried calling the stores directly? Not sure If they would even have it in stock. They would probably have to order them any way.

I bought a sheet of "cut your own" fiber gasket material a few years ago and they had to special order it for me. Took a few days.

 

Went o AutoZone today. The not so helpful rep searched up a few on the computer and none of them seems like they would hold up to 2 miles worth of driving.

I also went to a local performance shop. They had a few Vibrant pre-made gaskets in stock. Two metal layers sandwiching what I assume to be carbon/graphite. Good material, but their 3 and 2 bolt 3" gaskets wasn't close to fitting my flanges.

It's a MazSpot midpipe btw.
