Default Best header flange gasket

While doing plugs and wires, I noticed that my passenger side flange/collector gasket is partially blown out/burned and missing 2 bolts. Good gasket that I can pick up at a local parts shop?

If you add a signature with some info on your car it would be easier to help you.
Do you have SLP single cat headers or the dual cat version like these? There are vast differences between the two versions.


Single Cat SLP header. Two bolt flange to Y pipe with 2.5" donut gasket.

I haven't used a header or collector gasket in years. Strictly copper based hi temp silicone. Never have a failure.

Copper based silicone wow thats going to suck getting off if you ever need to disconnect header.

Use the stock style MLS gasket they can take the header coming loose and not blow out. I never use paper gaskets ever they suck and if the header ever comes loose while hot your replacing. Mls you just retight bolt and go
