I need an exhaust flange gasket with the three bolt holes but with 2 2.56 in ports. I have a gibson y pipe going into a dynomax muffler. The stock gasket 2.56 and a 2.75 inch holes keeps blowing out. I believe this to be the 2.75 in cutout is way to big for the 2.56 in holes its trying to seal. Anybody know of such a gasket?
