Any chance you guys could post some little clips of those puppies in action?

What did you guys think of the Supra clip?
Sounds pretty sick, huh?

My piecer. 14b, 2.5" exhaust.

I recently made a cold air intake that goes into the fender well.

It whistles alot louder now, then when I had a HKS style filter directly on the turbo. I don't know how much that has to do with the metal pipe, and how much it has to do with the filter being in the fender, which is alot less insulated than the engine bay. But the spooling noise is alot louder now.

By "open downpipe" are you talking about just a downpipe with no exhaust (no muffler or anything)?

my exhaust is completely open 3". not cat, no resonator, no exhaust, and yes, it makes the turbo MUCH more audible...

I've seen some people use something that almost looks like a regular screen door material...
Yup, most people use whatever kind of screen they can find. Screen door material works well.

But, the only downside is, you don't get any filtration and you can suck in dust, sand, dirt, or whatever... and that's not really a good thing.
