As anyone fitted an Exhaust Silencer to the above, if so where in the exhaust pipe did you fit it, does it matter?

I've got a Propex HS2000 that has a noisey exhaust, I've spoken to Propex and they recommend fitting the above, what I forgot to ask was where to fit it.TIA.

If it is like our Webasto it just fits on the exhaust from the heater and has nothing to do with the main vehicle exhaust. Think lawn mower exhaust. :)

He I understand it goes on the heater exhaust, but does it need to be in the middles of the exhaust pipe, or closer to one end or the other?

The normal guidance is to fit the exhaust silincer as close to the heater as possible... the pipe should fall away from the heater ...

Don't know but something tells me it fits on the open end like a chrome tailpipe on a car

Hi, the end of the tail pipe isn't wide enough to accept the silencer due to it having a end piece on, for want of a better description, but I've just found this picture which seems to answer my question.

end piece on,
Those end caps just screw on to the pipe end..easily removed and refitted if you need to re jig your set up..
If the metal pipes have been clamped and flattened its often easier to jost cut a little off and make a new connection..

IIRC the closer the muffler is to the engine and the longer the tail pipe the quieter it will be
it also pays to fit the inlet silencer as well .

Ok, I didn't realise that. I think I'll go with what's in the picture as the silencer would stick out of the back of the van leaving me nothing to fix it to if I put it on the end.

I just assumed it was normal its a lot quieter once it gets to temperature and throttles back a bit

Am I reading this correctly?, it would be better to put the silencer at the other end of the tail pipe where it exits van?

When I had an Eber I fitted the silencer at a convenient part of the exhaust (about mid point) where I had a good fixing point. I found the exhaust and the inlet silencers made quite a difference reducing the noise of the heater.

Cheers

the silencer needs to be as close as possible to the actual heater , and then as long a tailpipe as is needed to exit beyond the underside of the body , and clear of below windows or other inlets .

Thanks, I thought that was what you were saying, I'll get on with it if it ever stops raining.

One more question, does it matter if it's fitted on the vertical, or horizontal, my pipe drops out of the van about 10-12" before it bends, would it be ok to fit on the vertical part?

Yes... if you have somewhere to secure it...

From fitting these sort of diesel heaters to trucks I seem to remember that they run on a balanced flue system that means the inlet pipe is meant to be the same length as the exhaust pipe..
