Review on 🔧 Walker 31383 Gasket for Hardware by Alex Montgomery

I had to use an angle grinder with a cutting disc to loosen the catalytic converter and center exhaust pipe and then use a hand drill to drill out the studs. An exhaust leak followed. About a week later I applied this gasket as well as Permatex Copper RTV to the outer rim of the inner ring. 2 days later the exhaust leak still hasn't come back. The picture shows 8mm x 35mm (1.25mm spacing) bolts, not expensive OEM bolts. It is coated with a copper anti-seize coating. Although 8x30mm might have been a better choice.
