You have to be INSANE to have long-tube headers on a big-block A-body Mopar!

Got weened off of headers when I was 16 years old, working on my cousins '65 GTO. That was enough for me.

TTI 2 1/2" exhaust all the way out the back coming off the factory manifolds, great way to go.

Not dumping all that heat into the engine bay with the manifolds either, like the headers do. Plus I just like something that is nice to work on.

Actually ..engines run cooler with headers, faster heat dissipation from the tubes, more efficient overall..
Sometimes you have some really out there thoughts or ideas that you might wanna rethink over before executing them. I'm not intending to be a prik..but you influencing anothers decisions with fallacy is fk up.
