What is a True Dual Exhaust?
A True Dual Exhaust is a system with one exit point for each cylinder of an engine. Each head pipes from each side of the motorcycle’s engine exit to the rear of the bike. It is not just one exhaust pipe with two outlets; instead, the system has one pipe for every cylinder, regardless of whether the engine has two, four, six or eight inline or V-shaped cylinders. It means no gathering of the emitting gases at a single exit point. The dual exhaust system technically allows the engine to breathe better by creating a complete combustion cycle from the engine.

Dual Exhaust vs. Single Exhaust
A single exhaust pipe is a system with one exit head-pipe for all cylinders of the engine. They are usually lighter than dual exhaust systems. A single exhaust system frees up space under the bike, allowing you to fit it easily.
Dual exhausts are more popular because they increase torque, horsepower & performance. Naturally, they’ll cut you more than single ones. A dual exhaust system offers deeper, richer, and throatier sound at high speeds. If you want to buy an exhaust that increases your bike’s power output, converts its torque into horsepower, and gives it a stunning sound, then you should get a dual or true dual exhaust.
True Dual vs. Power Dual: What’s the Difference?
The True Dual is the quietest among the three because it has two or more mufflers, packing, and sound baffles to reduce noise. It’s the best option for Harley Davidson due to more volume of packing than power duals. True Dual exhaust systems are restrictive to the head-pipe and are not as loud as power duals, so they are good for people who want to ride at low volume yet with better sound quality.
Power Dual is the loudest among them because it has less volume of packing, no sound baffles, and no restriction in its headpipe. A certain number of riders like the Power Duals because they have an open head pipe, free-flow mufflers, and unrestricted flow.
2 into 1 Exhaust vs. Dual Exhaust
2 into 1 exhaust systems have 2 pipes that emit fumes into one muffler, helping to increase a bike’s power, performance, and efficiency, especially in the short term. That’s why they are most common for sport bikes. A 2 into 1 exhaust is lighter than dual exhausts. They are cheaper than their Dual counterparts.
Dual exhausts are the best choice for people who want to buy an expensive, high-performance exhaust. It makes your bike run at its highest performance, giving you more power and torque. A dual exhaust system is most common for touring and larger motorcycles. For instance, all Softail bikes have now Dual exhaust since 2018 with the introduction of Milwaukee 8 engine.
Does True Dual Exhaust Increase Horsepower? How Much?
True Duals are expensive, but they have significant power gains. They increase horsepower by about 10 to 25% by allowing the burned gases to exit your engine faster. They are more expensive than Power Duals. A True dual exhaust has free-flowing straight pipes that replace the restrictive headpipe.
Do Dual Exhausts Need Mufflers?
Yes, all motorcycle exhausts need mufflers to reduce the noise. Mufflers are also crucial because they keep the rider, passenger, and vehicles around it safe from exhaust leaks which can prove dangerous. Check out the best muffler for dual exhaust.
A muffler’s job is to absorb and dissipate harmful noise frequencies. It also keeps exhaust gases cool down. If you don’t have a muffler, it will make a really loud noise that can damage your ears and be a real hazard for pedestrians. Vance & Hines manufactures some of the best slip-on mufflers for true dual exhausts. You can check them out.
Why Get High-Performance Exhausts?
They are designed for increased power, torque & high-end driving performance. Usually, they are louder than stock motorcycle exhausts. You can identify them by chrome or titanium silencer and the reflective stainless steel piping of full length on both sides of the street bike’s rear fender tips.
Choosing the right exhaust for your Harley Davidson is an important decision. There are many factors and options to consider, especially regarding power, performance, noise levels, and price. You should always check the level of sound it can generate. Please make sure they do not damage your ears and environment.
