Lay the other two silicone buffers on top of the collec-

tor tube, in the places where the pipe clips are to be 

screwed on.

Insert the pipe clips on top of the new collector tube 

in such a way as for the screwholes to fit on the scre-

wholes of the housing.

Screw the pipe clips to the housing again but do not 

yet tighten them; first you need to align the new col-

lector tube properly.

Shift the new collector tube in such a way that the 

exhaust nozzles have the same distance from the 

housing on both sides. 

Now screw the pipe clips tight.
