I was running twin 4" stacks. Now i'm running a single because i discovered it runs cooler that way....

The stack or the truck?

EGTs run cooler. Not a huge amount, but as high as they are, every little bit helps....

The stack itself is hotter.

Hotter exhaust flows faster = better scavenging from the cylinder?
