Thank you for the heads up. Safety first! I have the 1.5 ton ones, and they have always seemed kinda flimsy. I am using old green jack stands that are super beefy and would hold the titanic up off the sea bottom floor LOL. QUESTION: Do you happen to know the torque specs for the Killer B manifold flanges? I torqued the turbo/outlet flange nuts to 40.5 ft.lbs and haven't torqued the inlet flanges yet. Thanks!
