exhaust leaks at manifold to up pipes

[PowerstrokeAaron]

Just got done doing egr and when i started it up i was checking for exhaust leaks with soap and water in a spray bottle before it got hot. It bubbles on both sides at the flanges where the exhaust manifolds connect to the up pipe and y pipe. Just wondering if anyone knows what i could do here, when it was apart I scuffed the mating surfaces with emery cloth to make sure they were smooth.

Mine is doing the same thing. Is that your only leaks? Can you hear it hissing and smell the exhaust in the cab?

use high temp silicone seal, time and rust will take care of the rest

no hissing or smell, just was checking everything over and this was all I found. Dont really feel like loosening the y pipe up by the turbo so I think ill just drive it for a while and then re torque and re check them
