Pipe Dreams: Exhaust Replacement Information and Reviews for 2 Into 1 Exhausts for Harley-Davidson Motorcycles

Your Harley-Davidson motorbike may be altered in a variety of ways, including altering the foot controls, handlebars, front fairing, shocks, adding a fuel controller, updating the tyres, changing the foot controls, and more. If you were to ask the majority of motorcycle riders what the #1 modification they would make to the next bike they bought, there’s a good chance that the unanimous response would be to install a different exhaust. There are a few modifications that motorcycle riders generally prefer that Harley owners should do after purchasing a motorcycle.

Motorcycle exhausts have two fundamental purposes: they muffle (quieten) the engine’s exhaust air, and in the case of systems with a catalytic converter, they also eliminate certain pollutants. The majority of factory exhausts perform their intended functions well, but they frequently add unneeded weight to the motorbike and rarely emit the ideal exhaust tone that is heard with free-flowing aftermarket installations. The debate over whether exhaust system is better or worse for a particular motorbike typically comes down to personal choice and objectives because the most popular aftermarket exhaust configurations are supplied in a range of different metals and designs.

If the stock exhaust works, why replace it?

Replacing the exhaust system of your motorcycle can offer functional benefits and improve overall performance. Whether your bike is older, has high mileage, or has experienced previous accidents, it’s possible that there could be issues such as leaks in the pipes or unseated gaskets causing exhaust leaks. Defects like bent pipes can negatively impact airflow and hinder the motorcycle’s performance, necessitating the replacement of the exhaust system with a unrestricted and unobstructed pipe. Additionally, replacing the exhaust system reduces backpressure from the engine, resulting in improved performance. Moreover, aftermarket exhaust setups are typically lighter than the original equipment manufacturer (OEM) exhaust, enhancing the bike’s overall weight distribution.

Enhanced Visibility and Options for Replacement

Furthermore, for riders engaged in lane filtering or lane sharing, aftermarket exhaust systems provide added noise that helps increase their visibility to car drivers, contributing to their safety on the road.

Exploring Replacement Options

If you’re considering replacing your exhaust system, it’s important to understand the available options. Aftermarket exhausts are commonly offered in three ways: slip-on or muffler-only, full exhaust, and modular systems.

Slip-On (Muffler-Only) Option: Opting for a slip-on exhaust involves replacing only the muffler section of the exhaust system. This choice is ideal if you seek a different sound and appearance for your bike without prioritizing significant performance gains. Slip-on exhausts generally provide a modest increase in horsepower.

By replacing your motorcycle’s exhaust system, you can address potential issues, enhance performance, and customize the sound and appearance of your bike. Consider your specific needs and preferences when selecting the replacement option that suits you best.


When you replace your factory exhaust with a complete system, everything from the heads downstream to the tailpipe is replaced. If you want to change your engine, race your motorbike, or want your exhaust to perform significantly better, this is the best option for enhancing it. But in order for the ECM and engine to work ideally with the new system, replacing the factory exhaust with a complete system would necessitate tuning the engine and/or making changes to the fuel management system.


More exhaust manufacturers are starting to give consumers this as a sales strategy. Modular exhaust systems are essentially whole exhaust kits that are available for purchase and installation in individual pieces. Instead of trying to pay for a fully constructed exhaust setup, which may be expensive for some people, individuals can purchase the improvements and install them at a pace that suits them both financially and in terms of time.

How do I know which exhaust to buy, or what will work with my bike?

  • When it comes to selecting the ideal exhaust system for your Harley-Davidson, the abundance of options can be overwhelming. To make an informed decision, consider utilizing these valuable resources while keeping your search engine optimization (SEO) goals in mind:

    1. Online Forums: Tap into the wealth of personal knowledge and experiences shared by motorcycle enthusiasts on web forums. Visit popular platforms like HDForums.com, v-twinforum.com, or hdtimeline.com, which boast large and active communities.

Frequently Asked Questions


The debate between 2 into 1 exhaust systems and 2 into 2 exhausts continues to spark interest among motorcycle enthusiasts. Proponents of the 2 into 1 design assert that the merging of pipes creates a slight increase in backpressure, leading to enhanced motorcycle performance and increased torque. This effect is achieved through an optimized airflow facilitated by the single combined pipe, setting it apart from the 2 into 2 exhaust counterparts.

When comparing 2 into 2 exhausts, the reduced back pressure in this configuration results in higher power at top-end higher RPMs. However, it does come at the cost of diminished low-end torque, which might not suit the preferences of some riders.

Beyond the performance aspects, the choice between 2 into 1 exhaust systems and 2 into 2 exhausts often comes down to the visual appeal on the specific motorcycle they are installed on. Some riders favor the sleek and unified appearance of a 2 into 1 design, while others prefer the distinctive look of 2 into 2 exhausts.

In conclusion, the decision to opt for a 2 into 1 or 2 into 2 exhaust ultimately depends on the rider’s priorities, with performance, torque, and visual aesthetics being essential factors to consider when customizing their motorcycles. Whichever option is chosen, it’s crucial to understand how each system affects the bike’s overall performance and tailor it to individual riding preferences.


You may see or hear the term “stepped headers,” which refers to the process of gradually increasing the pipe diameter from the head to the collectors to enable gases to flow more rapidly and eliminate an exhaust limitation source. If your engine also has a big bore kit, stepped headers are advantageous since you can get a bigger performance boost from the combination of the big bore kit, stepped headers, and an engine tune. The pipes of an exhaust system without stepped headers are all the same size and do not increase in diameter as they exit the heads.


Assuming that the exhaust installation is once more accompanied by an adequate engine tune to augment the improved airflow, equal length headers can provide a higher performance boost than uneven length headers. The majority of regular motorcyclists may not notice much of a difference between equal and uneven headers, however; those who are performance-oriented and who own race motorcycles will.


For the majority of slip-on exhausts, there is a model year compatibility window where a certain type of exhaust is accessible for a given generation from the perspective of bolt-on compatibility. Usually made and supplied expressly for your motorcycle’s year and model, complete exhaust installations replace the whole exhaust system, including the heads and tailpipe. However, since the exhaust kits are made using factory geometry, it’s possible that they won’t take into consideration any changes you make to the foot control placements. Aftermarket exhausts may provide a problem if you change your motorcycle’s stock mid controls to forward controls (or vice versa), as they are often built with the assumption that the rider’s foot controls are in a different place. The majority of new exhausts will benefit from an engine tune, and a fuel controller may be helpful in select high-performance applications.

In conclusion…

When it comes to enhancing the performance and riding experience of your Harley-Davidson motorcycle, upgrading the exhaust system is a highly recommended modification. However, it’s crucial to ensure proper installation alongside a tune to fully unlock its potential. Not only does an upgraded exhaust system improve performance, but it also offers a unique and distinctive sound characteristic to each brand’s system.

For optimal results, consider opting for stepped headers or full systems, as they deliver exceptional performance when paired with an engine tune or fuel management system. It’s worth noting that each exhaust system offers its own set of advantages and visual appeal. To determine your preference in terms of appearance and sound, seek insights from fellow Harley-Davidson owners who have experience with the specific exhaust system you’re considering.

If you’re unsure about which exhaust system to choose, refer to the comprehensive list provided above and explore the options that catch your eye. With careful consideration and successful installation, you’ll soon have a new exhaust system ready to unleash its power and provide an exhilarating experience during your future rides.
