Most customers are looking to improve four things when they pick up a new exhaust: performance, sound, weight and style. Adding a power commander to the equation is also recommended for getting the most out of your new pipes.
Full systems tend to offer the best performance, dropping significant weight and increasing horsepower. However, they may not provide the best torque for street riders.
Many riders want their motorcycles to sound more like Harleys, but achieving that deep purr with a street-legal exhaust can be tricky. Many areas have noise ordinances that restrict how loud a bike can be, while some manufacturers are hesitant to add catalytic converters or other emissions-related features to their pipes because of the extra cost and potential for problems.
Some believe that a bigger, more aggressive-sounding exhaust will increase power. This is not the case, says Danny Valencia, operations manager at Two Brothers Racing. He explains that the engine designers and engineers must balance performance and fuel efficiency, reduce back pressure, scrub hazardous compounds from the Best slip on motorcycle exhaust Radiant Cycles and create a design that looks good and fits inside the frame and luggage.
A big exhaust can actually reduce power by creating too much backpressure, limiting air flow. That is why most manufacturers, including the original equipment makers, use the shortest headers possible without creating too much drag.
For OEM motorcycle manufacturers to create their bikes, they must balance the designers’ aesthetic desires with the accountants’ cost demands and the engineers’ performance requirements. This often means the exhaust system is constructed with heavier materials. A lightweight replacement exhaust can reduce the weight of your bike, allowing you to use less fuel and improve acceleration.
The most common exhaust material is aluminum alloy, which is both lightweight and durable, ensuring that your new exhaust will last. Stainless steel is also an option and is resistant to corrosion.
Some full exhaust systems may require you to replace oxygen sensors or relocate components like side stand bumpers. Be sure you have all the required tools to install the new exhaust before you buy it. You don’t want to be halfway through a project and realize you’ve lost that 8mm allen wrench your buddy lent you. In some cases, it is necessary to have a professional tune the bike when installing a new exhaust.
The exhaust is an integral part of your bike, protecting the engine from overheating and reducing sound to acceptable levels. It also scrubs dangerous compounds from the engine and keeps the environment clean. It must do all of this while being durable, aesthetically appealing and within budget constraints and emissions regulations.
A good aftermarket exhaust will improve performance, but it’s important to pick one that fits your specific needs. Some exhausts are better at maximizing power at high rpm, while others are better at low revs.
Exhausts made from stainless steel are popular because they’re strong, durable and look great. You can also get carbon fiber and titanium exhausts that are lighter and more expensive. These can be more difficult to keep looking new, but a good way to prevent staining is by purchasing pipes that feature extensive heat shields. These effectively add a pipe within a pipe, so the visible pipe never achieves the high temperatures that the inner pipe does.
The best motorcycle exhausts are sleek and stylish. They are often made from stainless steel, titanium or aluminum which is lightweight and durable. Depending on the manufacturer they may also use a coating to protect the pipes from corrosion or rust.
The Two Brothers M2 Black Series slip-on is an excellent choice for riders who want a powerful, high-performance exhaust that looks amazing on their bike. It has awesome sound delivery, a free heat shield and an easy-to-install design. It is also one of the most value-packed options on the market.
The main reasons customers choose a new set of pipes are for better sound, weight and performance. Full systems are typically a good option for racers and enthusiasts who want to maximize engine power. They can also take a lot of weight off the bike, which is important when racing. However, they require a reworked fuel system and may cause the engine to become “lean” at certain RPMs.
