TTI Shorty Headers For Small Block - Anyone Try Them Yet?

The shorty headers I've seen need such a tight bend at their outlet that would appear to be a restriction in itself,, don't know the brands either..

I would just like to bring to attention,, you can get a ceramic Doug's long tube header, that are ground clearance friendly for over a hundred dollars less,, and includes free shipping.. From Autozone,, when they have their 20% off sale..

hope it helps
