I ordered one for my big block '72 from Stainless Works. 3" SS from the headers back and they recommended their two chamber turbos when I told them I didn't want small children and animals to run when I started the truck. Basically my wife will drive it - she loves rumble/some thunder, but she won't drive it if it's too loud.
Seem solid to deal w/ so far, they do have some lead time...and the bill was a little ugly - but SS won't ever rust out and it's mandrel bent very nice stuff.
Jury is out...I'm confident at this point..and hoping.
