A series of unfortunate events

[Tempted]

-TBI is NOT open plenum, its a dual plane intake
-True duals dont cause a problem at all, dont know where you got that idea, but they dont, yes they arent the best idea for exhaust, but it isnt gonna cause issues.
-from what i been told, Black Smoke usually means over-fueling

I see two holes that feed into one plenum....

An exhaust without a connection won't cause a truck not to run, it will cause a loss of power.

I said black smoke means fuel isn't usually an issue.....
