    How did you guys with powerlogs get it to seal at the crossover? My stock manifold didnt have a gasket and I even checked in the parts dept at work to make sure it didnt come with a gasket from stock. From factory the manifold does not have a gasket there. My powerlog leaks like crazy. I used high temp rtv but its too flexable and blows out when I boost. So how did you guys do it?

    Try loosening both crossover pipe connections at the manifolds/powerlog first, wiggle crossoverpipe around till it fits good at both ends, retighten bolts. Tighten boths end gradaully, a little at one end, then a little at the other end, repeat.
    This is how I installed mine, it seal fine with no RTV.

    Check the parts store. You are looking for the exhaust crossover gasket. Mine is leaking as well. I need to go back and install the gasket.
