True Dual Exhausts for Harley – Buyer’s Guide!

Written by James Smith

When replacing an exhaust system you are faced with a number of decisions; these include whether you buy a complete kit or a slip on muffler, and then you need to decide whether to buy a true dual exhaust system or a single system that splits into two.

The advantages of a true dual exhaust system are that it takes the dual exhaust system utilizes two separate exhaust manifolds (headers), 2 or more catalytic converters, 2 mufflers and 2 separate exhaust tail pipes. As such, you do get better performance, better looks, but it does cost you a bit more too.

The only downside in a separate dual system is that the gases leaving the manifold can de0syncronnize with each other, as such you might get more torque and power from one cylinder over the other. To combat this, a crossover pipe is added that allows the exhaust to mix with each other and maintains an equal pressure and performance from both manifolds.

A true dual exhaust system will definitely increase your engine’s performance and as such increase power and torque. When adding a true dual exhaust, you are introducing a performance upgrade which changes the way your ride performs.

Now that you have decided to ramp up your bike and turn it into a power hog, let’s take a look at the best true dual exhaust for Harley Davidson on the market today.

Conclusions

This list was fun to build, only because I got to try out over 50 different models of the exhaust on a select number of bikes. The bottom line is that these five are the best for their applications. Now I know that looks are subjective, but you cannot argue with performance. Price is also subjective since rich people have no issues while us more economical challenged citizens need to consider every cent we invest in our rides. As such, there are hefty prices in this list; I could not honestly create a list of cheapo items, it would be a lie and would not give you the goals in life to achieve. Five more for the bucket list.
