An exhaust system designed and manufactured by a third-party company for the Husqvarna Svartpilen 801 motorcycle, intended to replace the original equipment manufacturer (OEM) exhaust. These components are often sought to alter the motorcycle’s performance, sound, or aesthetics.
Replacing the factory-installed exhaust can yield several advantages. These include potential improvements to horsepower and torque output, reduction in overall weight, a more aggressive exhaust note, and a customized appearance to enhance the motorcycle’s visual appeal. The availability of such components provides owners with options to personalize their machines beyond the stock configuration.
The following sections will delve into specific performance enhancements, acoustic properties, aesthetic considerations, and factors to consider when selecting a replacement exhaust system for this model.
1. Enhanced Performance
The integration of aftermarket exhaust systems on the Husqvarna Svartpilen 801 is often pursued to enhance engine performance. These systems are designed to optimize exhaust gas flow, potentially unlocking power gains beyond the factory configuration.
-
Optimized Exhaust Flow
Aftermarket exhausts frequently feature wider diameter piping and less restrictive mufflers. This reduction in backpressure allows the engine to expel exhaust gases more efficiently, potentially leading to increased horsepower and torque, particularly in the mid-range and top-end of the RPM spectrum. The efficiency of this flow is a critical factor in achieving tangible performance benefits.
-
Weight Reduction
Many aftermarket exhaust systems utilize lighter materials such as titanium or carbon fiber, offering a reduction in weight compared to the stock exhaust. This weight reduction contributes to improved power-to-weight ratio, enhancing acceleration and handling characteristics of the motorcycle. The extent of weight reduction varies depending on the materials used and the design of the system.
-
Engine Management System Compatibility
To fully realize the performance gains from an aftermarket exhaust, it is often necessary to remap the engine’s electronic control unit (ECU). This recalibration optimizes fuel delivery and ignition timing to match the new exhaust system’s characteristics. Incompatible ECU mapping can negate the performance benefits and, in some cases, lead to engine damage. Some exhaust manufacturers provide pre-programmed ECU maps or recommend specific tuning procedures.
-
Dyno Testing and Validation
Reputable aftermarket exhaust manufacturers conduct dyno testing to quantify the performance gains achieved with their systems. These tests provide data on horsepower and torque increases across the RPM range, offering potential buyers empirical evidence of the exhaust’s effectiveness. Independent dyno testing is also valuable for verifying manufacturer claims and ensuring the exhaust meets performance expectations.
The potential for enhanced performance with an aftermarket exhaust for the Husqvarna Svartpilen 801 is contingent upon selecting a quality system, ensuring proper installation, and potentially adjusting the engine’s ECU. Carefully considering these factors is crucial to realizing the desired performance improvements.
2. Sound Customization
The modification of exhaust systems on the Husqvarna Svartpilen 801 frequently extends beyond mere performance gains, encompassing the significant aspect of sound customization. Aftermarket exhausts offer a range of auditory profiles, allowing riders to tailor the motorcycle’s sound to personal preferences.
-
Muffler Design and Construction
The muffler is the primary determinant of an exhaust system’s sound characteristics. Aftermarket options vary widely in internal design, including baffled configurations, straight-through designs, and resonated chambers. Material choices, such as stainless steel, titanium, or carbon fiber, also contribute to the overall sound. A baffled muffler generally produces a quieter, more controlled exhaust note, while a straight-through design yields a louder, more aggressive sound. The construction quality and internal volume further influence the tonal qualities of the exhaust.
-
Exhaust Note Frequency and Volume
The frequency and volume of the exhaust note are key factors in sound customization. Frequency refers to the pitch of the sound, while volume denotes its loudness, typically measured in decibels (dB). Aftermarket exhausts often alter both parameters compared to the stock system. Riders may seek a deeper, more resonant tone (lower frequency) or a louder, more attention-grabbing sound (higher volume). Regulations concerning noise levels vary by jurisdiction, requiring riders to ensure compliance with local laws.
-
Catalytic Converter Presence or Absence
The presence or absence of a catalytic converter significantly affects the exhaust’s sound and environmental impact. Removing the catalytic converter generally increases exhaust volume and alters the tonal characteristics, often resulting in a raspier or more aggressive sound. However, its removal can also lead to increased emissions, potentially violating environmental regulations and affecting the motorcycle’s legality for street use. Some aftermarket exhausts retain or incorporate high-flow catalytic converters to mitigate these concerns.
-
Resonance and Drone Mitigation
Resonance, often referred to as “drone,” is an undesirable low-frequency hum that can occur at specific engine speeds. Certain aftermarket exhaust systems incorporate design features, such as resonators or Helmholtz chambers, to mitigate resonance and improve the overall riding experience. The effectiveness of these mitigation strategies varies depending on the exhaust design and the motorcycle’s characteristics. Addressing resonance is crucial for maintaining rider comfort, particularly on long journeys.
The selection of an aftermarket exhaust for the Husqvarna Svartpilen 801 allows riders to carefully sculpt the motorcycle’s auditory signature, achieving a sound profile that complements their riding style and preferences. The balance between desired sound characteristics, regulatory compliance, and potential performance impacts requires careful consideration.
Conclusion
The exploration of Husqvarna Svartpilen 801 aftermarket exhaust options reveals a multifaceted landscape where performance enhancements, acoustic customization, and aesthetic considerations converge. The potential benefits of replacing the factory exhaust system, including improved horsepower, reduced weight, and a personalized sound profile, must be weighed against factors such as cost, installation complexity, and regulatory compliance. Careful selection is critical to achieving the desired results without compromising the motorcycle’s reliability or legality.
The decision to invest in an aftermarket exhaust for the Husqvarna Svartpilen 801 should be grounded in a thorough understanding of available options and their implications. Whether the goal is to unlock additional performance, refine the motorcycle’s auditory character, or enhance its visual appeal, informed decision-making remains paramount. Prospective buyers are encouraged to research thoroughly and, where possible, consult with experienced technicians or fellow riders to ensure that any selected exhaust meets their specific needs and expectations.
