Default Exhaust flange nut torque

I'm installing a Corsa system tomorrow. Does someone know the factory torque setting for the two flange nuts at the front of the H-pipe?

The Corsa instructions are great, the give all the torques except that one.

Thanks

I always used my small air gun at the middle setting. Didn't realize that a torque setting on anything involving exhaust was inportant. I think that they should be tight enough not to rattle loose.

Be careful with those four studs. They bend very easily when removing the old exhaust.

I think you are looking at the wrong spec. The spec in question is the "Intermediate Pipe to Catalytic Converter Pipe Nut". 12 ft-lbs. Page 9-781 of the Service Manual.
