gimpydingo Posted August 10, 2017 Share Posted August 10, 2017 EDIT: I will be ordering these and trying to flatten the surface more: http://www.grimmspeed.com/grimmspeed-exhaust-manifold-to-crosspipe-gasket-pair-2x-thick-subaru/ http://www.grimmspeed.com/grimmspeed-exhaust-manifold-to-up-pipe-gasket-2x-thick-subaru/ Added pics of my exhaust manifold. So close to getting everything wrapped up with this car. 07 LGT. Ever since I installed my DP and replaced the gaskets for the DP, UP, and exhaust manifold, I am getting leaks. Unfortunately the UP to exhaust mani gasket and the crossover (I guess that's what it's called) from the passenger mani to the driver side (near the UP to mani gasket) is leaking as well. My exhaust manifold has rust and some light pitting around where the gasket ring sits, which is probably the main culprit. In process of a tune (isn't that always the way) and noticed a bit of lag and my numbers out of whack. I've seen black streaks on the gaskets and today did the soapy water and start the engine trick and yep leaky leaky. I see grimmspeed has 2x thicker gaskets. Any other suggestions or suggestions on how to put everything back together; which order to tighten the various bolts. Should I leave the UP untightened until the end, etc...
