Dual Exhaust Vs Single for Trucks
Properly implemented, either single or dual exhaust systems can perform well on most any truck. The question largely comes down to matter of perence in sound, appearance and budget.
Horsepower
Horsepower is a matter of exhaust flow, and it matters little whether that flow issues through one big pipe or two smaller ones.
Sound
Because dual pipes split the flow, it is easier to hear the sound of individual cylinders firing. Many people per some sort of dual exhaust for their more analog exhaust note.
Budget
Most people who replace a trucks exhaust system will opt not to use a true dual exhaust system, because often the entire system must replaced, from exhaust manifold to tailpipe.
Velocity and Torque
If there is one good argument for dual pipes, it is that using two smaller pipes will cause an increase in exhaust velocity, which may help boost torque for towing.
Turbodiesels
Almost all turbo-diesel trucks work best with a single large exhaust pipe, since the turbo only has one large exhaust outlet anyway.
