Exhaust conversion
« on: October 08, 2018, 07:24:08 am »
I have a 76 750k , bought an exhaust for it , found that the new exhaust is for a later model. (77-78). I bought the studs , split collars , and flanges and of course the crush gaskets. I’m not exactly sure how these collars and flanges work together. Any help with this conversion would be greatly appreciated .

Remove your spigots, dig out old crush washer.
 Install studs.
 Slip finned collar over the pipe, then add two half round bushing .
 Make sure they catch the step in the collar, then tape together with masking tape.
Slide into the port, add nut and washers, tighten them up..done..

A couple of pics may help.

 Start right out using an impact driver and a good fitting bit getting off the old spigots off if they are still there so you don't mess up the head of the screws. Sometimes they come out fairly easily and sometimes they can be a pain.

 Lookswise I favour the early style mounts.. spigots
 Quicker pipe removal, cleaner looking whith slimmer clamps. Check The pic

One drawback  pope to port match is not as good.
