400/4 Exhaust Fitting Info needed

(1/4) > >>

THUNDERDOWNUNDER:
I have inherited a set of replacement Pipes and collector box (Silvers ) for 400/4 . All brand new but no instructions . The pipes are marked 1 2 3 4 . My question is which way round do they fit the collector box ? I see on one side of said box has a fitting for a retaining bolt ( I don’t have ) The other three slots have nothing to hold pipes . So looks like press fit ! Any help welcomed.

I've got the same set on mine. The clamp on the collector is on the underside,  this puts the silencer outlet to the outer righthand side of the bike. The pipes are obvious then. The longest pipe goes from furthest cylinder to corresponding collector inlet and so on until shortest pipe goes from righthand cylinder to the righthand collector inlet. I used some exhaust paste on the push in pipes to make sure they sealed.
See Gallery photo of my CB400F Cafe racer 2.

Ps. It's a bastard to fit!

I just remembered,  Fit the silencer to collector box first, helps to line up the mounting points.

Thanks taysidedragon , invaluable help there . Yes I was thinking of useing a bit of heat on the collector box to help get the pipes in as they seem reluctant to fit . Did you push them to a stop or is it see how you go ? Hope you didn’t get any leaks .i wonder if the clamps (Silvers )are selling would help seal it ? Rob .

Clamps won't do anything as there is no slots on the other three inlets on the collector.

Had a go at fitting down pipes to collector box . No Luck  . If they are this hard to fit they aren’t going to leak that’s for sure !
