As of right now I am running SLP LM1 with catted SLP X. I still have the stock manifolds and there is a leak where the X meets the manifold on the drivers side. Is there anything I can do for that, or is it just cause they don't match up right? The

when I installed my MRT H the directions said to apply a small bead of high temp rtv on the drivers side flange when installing, maybe you forgot to do that?

the shoulders on the stock studs are probably preventing the midpipe from sealing with the manifold. i had the same problem so i replaced mine with these

Thanks for the hints guys. I didn't install the X, so I don't know if the guy who did out the rtv on or not.
