Do these exist?

The Warpspeed Performance website displays (photos and pricing) only aluminized steel.

I've emailed Warpspeed and asked the question ... haven't heard anything back yet and thought I'd search out some feedback here.

 

I spoke with them over a year ago and was told they are no longer available, even if I wanted to special order.
Aluminum is it.

 

Chitty ...

Much obliged for the info though.
