Is a true dual exhaust better?
Herein, what are the benefits of true dual exhaust?
Because the exhaust gases exit each manifold through two pipes rather than just one, they can exit the engine faster and provide additional horsepower gains. Dual exhaust systems help reduce backpressure, which can save energy and increase the engine's efficiency for better gas mileage.
Also, is true dual exhaust louder? The simple answer is yes, any true dual system is louder than the same system that has a crossover pipe. A crossover pipe does two things, it increases torque & it changes the frequency of the sound. There are twice as many exhaust pulses in both pipes with a crossover.
Just so, does true dual exhaust work?
A street view of this type of exhaust setup would lead one to believe that the vehicle has true dual exhaust but in fact, it does not. A true dual exhaust system would SEPARATELY utilize two exhaust manifolds or headers, 2 or more catalytic converters, 2 mufflers and 2 separate exhaust tail pipes.
What is true dual exhaust?
In lamens terms, true duals are both exhaust pipes ran by themselves, not tied into one with a Y pipe.
