? about homemade ram air
Alot of people including myself have used the dryer outlet duct because its either 3 or 4 inches and very bendable. If not I think you can also get some pvc piping, and if you have a torch, you can slowly bend to shape (kinda feels heavy to me though) Hope that helps

I just changed mine and I think deleted the pictures but Home Depot has 4" Black Flexible Plastic Sewer Pipe that does work, I used it on my previous set up (Biiiitch to get in though)
What I have now is 3" Stainless Steel



You can use regular 3" flu pipe, it's very cheap. You can get it at any Plumbing Supply or Home Depot.

You should be able to get thin wall pvc at any builder suppliers (ie Home Depot). Look for the tubing used for central vac's or in-ground sprinklers systems. An open flame is not a good idea to heat the pvc with (it localizes the heat to much to really work with). It can blister the tubing, leave it burnt looking and that's not saying anything about the toxic fumes and gases given off when it does burn. Use a heat gun and heat an area at least a foot long at a time to make the bend you want.
