Who has cool tunnel extensions

[ANDY SAIGER]

I put a 154 under my 146. I'm looking for a cool tunnel extension. I ordered one from Van Amburg because thats the kinda thing i want but they are out of stock and are a 3-4 week wait. I have a trip planned on Nov 30 so I'm cutting it really close. I want something more then just a plan piece of aluminum.
Any suggestions?
Thanks
