Yoshimura Exhausts and Yoshimura Parts
Yoshimura has established itself as one of the top dirt brands and suppliers of dirt bike parts since it began producing exhaust systems and modified engines in 1954. Back then Yoshimura tuned a wide variety of engines, but it soon started to specialize in exhausts as it began evolving into the manufacturer of some of the most sought after high-end exhaust systems, accessories, and parts available today on the market.
Yoshimura exhausts are manufactured for just about any dirt bike you can imagine. Yoshimura is known for producing one of the world's most power-focused, lightest dirt bike exhausts systems. Providing you the ideal mix of style and hard driving high performance, it's no wonder that Yoshimura hard parts, headers, engines, and exhausts are helping dirt bikes all over the world run faster.
One Yoshimura exhaust that has won the hearts of factory race teams is the Yoshimura RS-9D. This exhaust from Yoshimura has been designed and tested by professional AMA riders like Jeremy McGrath, Justin Barcia, Trey Canard, and Eli Tomac to ensure these race teams are getting those most out of their Yoshimura exhaust. The header produces a snappy throttle response while delivering an increase in power that is usable throughout all gears. Improving the mid-range to top-end power is the vertical divider that splits the exhaust gases for a smoother and more powerful exit. On top of that, the Carbon end cone gives these Yoshimura pipes a flashy finish and come in three different metals: aluminum, titanium, and carbon fiber.
Yoshimura slip on exhausts
Yoshimura slip on exhausts give you serious bang for your buck. A Yoshimura slip on exhaust is an awesome way to replace your stock muffler, because it's easy to install, cheap, and offers a notable upgrade. Just bolt on the slip on and you'll lessen the restriction of air flow from your engine, producing more power, a small reduction in weight, and a seriously aggressive look and sound.
Yoshimura produces slip on exhausts that are convenient unlike full systems: Yoshimura Slip On exhausts can be used without any kind of adjustable, aftermarket fuel controller or different fuel map. This is because they do not increase the exhaust flow out of the engine enough to need extra assistance to function properly. Of course you can make adjustments to your bike's fuel mapping and/or use a fuel controller along with a Yoshimura slip on to smooth out the rough edges produced by the torque and power.
One of the more popular exhaust systems from Yoshimura is the Comp series RS-4 slip on. Providing riders with a dirt bike exhaust system that will produce adequate power and an ear tickling sound, this Yoshimura exhaust is race tested and race proven to satisfy you. With a lightweight construction, this Yoshimura exhaust produces more mid-range and top-end power without exceeding the sound DB outputs.
One of the first aftermarket upgrade that many MX enthusiasts go for is the aftermarket exhaust. Yoshimura exhausts are one the finest choices available for this upgrade. Here's how it works.
Your factory made bike is designed to meet standards and regulations that control emissions and noise. These vary from place to place, but the common goal is to produce less noise and a smaller amount of emissions, which are the byproducts of your engine's process of burning fuel and producing power. This means that newer dirt bikes come with larger, quieter mufflers as well as catalytic converters that are heavy.
Yoshimura exhausts, like other aftermarket products, produce more power, less weight, and more noise because they are far less restrictive of air going through the bike. Yoshimura full exhaust systems are restricted for use on the track of off-road, and are not meant for road riding. These powerhouse systems usually include a less restrictive muffler, a mid pipe that in place of the catalytic converter that comes stock, and a lighter header pipe.
To use this kind of full exhaust system, you'll typically need a different fuel map and some kind of adjustable, aftermarket fuel controller. This is due to the greatly increased outflow of exhaust from out of the engine.
