exhaust flapper

[Defender=1st]

hey everyone i was thinkng of making an exhaust flapper (like a truck) for my Defender. would doing this cause any problems ?? would it effect fuel economy ?? would it matter if after a long run the exhaust pipe was covered stright away when the flpper goes down ?? would it matter if any gases in the pipe were still in there after a run
Thanks

I've been thinking about this too.
A mate of mine with an exhaust business rockons you should just buy one from a wrecker. I think he said toyota Dyna or some swear word like that. As long as it is the right diameter for your exhaust.
I am interested to hear any feed back as well.

What does an exhaust flapper do?

Look Cool :D

plus i park on a hill backwards so it will stop water in the exhaust (well thats my story and iam sticking to it :p)

It just stops the rain getting in vertical exhaust pipes as on trucks and earth moving gear.

OK - thanks. I was thinking exhaust brake which was way off the mark

The truck industry calls them rain hats.

It'd stop water being sucked into the engine if you stalled in a river crossing...
Or is that just a myth? :confused:

Any Ag Place that sells tractor bits can get them in for you. These ones just bolt on.

any ideas on a better mount than a hose clamp ??
i had to put rubber under the clamp to lift it because the end of the exhaust curls out and the mount had to sit level with the hinge i used. any ideas of a better/ more presentable mount ?? it has to sit high on the pipe so its level with the curl in the pipe. any ideas would be great.
it looks good from a distance:p

As others have said try a truck parts outlet, they're called Rain Caps, and you can get them in Galv or Stainless. You can also get ones that are silent and don't make a clanking sound when closing. You will need to provide the OD of the pipe, off the top of my head the smallest I think there is, is around 63mm.

You may also have to cut off that bit at the end. Check whats available first.

They are used on high vertical exhaust stacks to keep the weather out. There is no other purpose for them. On a normal horizontal tailpipe they are as much use as a sheila at lodge, or a shearer in a cattle camp.
