Installing catalytic converter - tightening torque and sequence

1)	Fit catalytic converter to turbocharger and fit screw-type clip -arrow- without tightening
2)	Loosely screw in bolts -3, 5- and bolts -1, 2, 4- by hand	It should still be possible to move catalytic converter and bracket.
3)	Tighten screw-type clip -arrow-	15 N·m
4)	Tighten bolts and nuts in the sequence -1 ... 5-	20 N·m
