Exhaust leak? What should I do?
While I’m waiting for my Racing Beat muffler, I decided to paint my mid-pipe I noticed a small leak on the gasket. After I painted the pipe I sanded the flange and noticed a small indent in the flange, used some copper gasket spray and it don’t look like its fixed. Should I use another gasket or type of gasket paste?

Yeah, shutup kid.
At work we use some thick black exhaust sealer, works great for exactly what you need it for. I'm not sure exactly who makes it, or if it will stand up to the extra heat from the rotary being that close to the engine, but I know it comes from napa in a white tube with blue and black lettering.
Your other option is to lay a straight edge across it and use an angle grinder with a sanding disc to take off the high spots. You might want to do this and use the sealer if the gap is big.

It’s a new gasket from Racing Beat the min-presilencer only has 200mi on it, The flange is flush except for that what I took a picture of (it’s kind of beveled there) almost looks like it was meant to be there. Directly above that on the other side it a little pitted looks like rust was there but I cleaned it and have a good seal. Mazdadave anything else, do you think if I put a wield in there it might give me a fix. I'm kind of lost with this, the only option I thought of other then this is welding a new flange or replacing the pipe all together.
I'll keep you posted Stu, my muffler should be here today. After a nice drive I'll see if it fails.

my guess is that the flange on the midpipe has warped and the flange on the presilencer is good. i surface all of my flanges on a large belt sander a a freind's machine shop. with thisif you can get a hand sander with some coarse grit you may be able to flatten it back out. i would put a level or a straight edge on the muffler flange to confirm if it has warped slightly. welding will give you a fix but will be difficult to remove should you have to remove the mid pipe.

every muffler shop ive ever been too has a BIG grinding wheel/belt sander, its job? to flatten flanges after weldong.
either sand it flat by hand the hard way, or bring it to a muffler shop, and give em moneys so they can buy the head of the neck
