Best header flange gasket
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.

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
