t-rex scale bell jet ranger exhaust question

[trexlover21]

I have a new Bell Jet Ranger body and I can't find anything to use as the exhaust pipe out the top. Any experience out there for a material to use for this? Thanks for the help.
As a side not this heli will be used in a spoof promotion for a local television station so I will post the video here when it is done in a month or so.
Cheers

Make it out of balsa and contact cement either aluminum foil to it or use some of that metalic duck tape around it.

You could make them out of foam or cardboard and cover with the chrome trim tape... They would be much lighter I would think....
