Mounting a canister exhaust system in the Extra 330SC is pretty
straight forward. Obviously there is a large selection of canisters on
the market to purchase. During assembly we used KS86 canisters.
However there is enough room in the fuselage to accommodate most
brands and styles of exhausts. Adjustable headers were also used to fine tune the positioning of our canister. Adjust-
able headers such as those produced by MTW and KS really make the canister installation process much easier. If you
wish to use readymade headers you will need a set with a 75mm drop.

Mask off the bottom of the engine dome in
preparation for marking out the desired cut out
area. Again the area that needs to be cut out
will vary dependant on your exhaust selection.
It s important with a dual canister installation
that you keep the centre seam area intact, try
and leave at least 20mm on either side of the
seam uncut.
Use the engine dome centre seam line as a
reference for marking out the area that requires
cutting out. As you can see from the pictures,
we removed an area 70mm x 110mm. This
gave us plenty of room to pass the canister
through, and allows air to flow in and around the
canister. Use your Dremel tool with a suitable
cutting burr to cut out the area you have marked
out. Don t forget to use safety glasses and a
face mask!
Canister mounts are part of the undercarriage
former, we have also supplied a second set of
canister mounts to suit a smaller diameter can-
ister. If your canisters need the smaller mounts
simply screw these directly to the existing
mounts!
