Inputs on piping material...

Hey guys, I've been working on my ongoing 11-second project car and I'm stuck on intercooler piping. From what I have found, 6061 Aluminum pipe is going to be the lightest and cheapest(if it wasn't for the weight, muffler pipe could be used). However, I was wondering if there were any more possibilities for my intercooler setup? The material needs to be able to be rolled into a diameter of no more than 3'' and withstand temperatures of up to 300F without warping or bending.

Anyways. This isn't anything dyer important, as I am most likely going to end up using 6061 Aluminum due to feasibility. However, I would like to get some input from people who base their livelihood off of this stuff, not just read about it on the internet.

Thanks.
