Weight and backpressure generally is what i'm curious about here

It'd be great if you had a scan gauge or something to add to the test

I was just wondering about if any of these will change fuel economy

1) Stock Exhaust
2)Stock exhaust with turndown at axle
3) Aftermarket muffler with turndown

This might not make much of a difference but it'd be different to see if it makes ANY

I'm thinking it probably would on a newer Dodge truck since they have that second big resonator at the end

But once again would anyone with a truck be willing to do this expirement
