I purchased an AEM intake for another Honda model which other 2nd gen Prelude owners said would fit, but of course it doesn't. In order to make if work, I need to obtain ~ 1 - 2 ft of 2.75" aluminum tubing. I've done many searches but have yet to find this size tube available anywhere. I even called AEM to see if they'd sell me some, but they wouldn't and suggested using exhaust pipe. I went to a local exhaust shop and while the pipe is 2.75" in diameter, it is very heavy and thick. Any ideas?
