Review on 🚀 Enhance Exhaust Performance with Mr. Gasket 5971 Ultra-Seal Collector Gaskets - 2Pcs by Isaac Simpson

I took a real risk not knowing the manufacturer of my manifold and had a hard time measuring the bolt pattern when assembled (didn't want to take the manifold apart until I it had something in my hand to put back) but they were perfect for me. Nice, thick and feels high quality. Seal the leak well!
