I have a 2018 charger 392. I need the torque specs for the collector studs where the factory manifolds bolt to the factory mid pipes. I replaced the graphite gasket but it's leaking, I'm thinking I over tightened it.

I think they are only 37ft lbs.... hold on

nope, the band clamps are 37ft lbs after the mid pipes.
the mid pipe to exhaust manifold nuts are 22ft lbs

Awesome thank you. Would you do that cold, then again after warming up? Or just cold.

It is always good to check torque again after a week of driving, but nobody does. I would just go 22 and be done with it. Make sure you tighten them evenly.

Ok. I have a wide band sensor right after the collector right before the cat and I put a new gasket on when I welded the bung in but I definitely cranked them down way too tight and probably caused a leak cuz I'm reading lean on the wideband.

Makes sense.
