well my road signs are deff aluminum. i have a huge one that i got from the old wilson dodge place that i was going to cut and make a flat bottom tray out of for my car. i had a splitter on my ae86 that was made out of a hyw 49 sign. i use what i can get my hands on. i didn't steal any of them i wait till i see them putting up new signs and pay off the road crew for the big ones.

I have some .040" thick 7475 Aluminum Im using for this stuff,under shrouds and the like.I got it cheap,you really cant weld it well and I doesnt like to be bent either.But it is light and stiff.I have no Idea what it would cost to buy on the open market..Edit:$147.50 for a 4'x8' sheet from aircraft spruce

very true but wouldn't that mean when you lift off the throttle it would interupt the "flow"?? or the more exhaust there is the more thats being forced out the diffuser and at some point it would creat some unwanted turbulence. might not be the best idea for the high hp, high exhaust flowing turbo guys. if im wrong let me know. these are just my
