The Dual Outlet Motorcycle Exhaust is a dual-outlet exhaust system specifically designed for optimized rear exhaust systems in motorcycles. The main body is constructed of aluminum alloy with a surface-strengthened finish, resulting in a lightweight yet robust structure. The dual-outlet design allows for smoother airflow, delivering a direct, linear exhaust response and providing riders with clearer power feedback during acceleration. Optional aluminum or carbon fiber heat shields are available to enhance safety and comfort during extended rides. The system boasts broad compatibility, working with a wide range of mainstream motorcycle models, ensuring a stable, reliable, and well-integrated user experience.

1. Aluminum Alloy Body
The main body of this Dual Outlet Motorcycle Exhaust is made of aluminum alloy, with a material density of approximately 2.7 grams per cubic centimeter. Compared to stainless steel, it is significantly lighter, reducing the overall vehicle weight by about 2 to 3 kilograms. Aluminum alloy typically has a tensile strength of over 150 MPa and excellent corrosion resistance.
2. Dual Outlet Structure
The dual-outlet exhaust channel design significantly reduces exhaust pressure within a single pipe, lowering engine exhaust resistance by approximately 20% to 30%, thus improving exhaust flow. The dual-outlet layout also allows for a more even distribution of exhaust airflow, reducing heat buildup and improving overall durability.
3. Precise Interface Size
The interface diameter is 51 mm, compatible with most mainstream motorcycle rear exhaust pipes. 51 mm is considered an international standard for sports exhaust interfaces, ensuring that the exhaust will not leak or become unstable due to interface mismatch. This size provides compatibility with a wide range of models, eliminating the need for additional adjustments to the connection when changing exhaust systems.
4. Optional Heat Insulation Cover
The heat insulation cover is made of aluminum alloy with a thermal conductivity ranging from approximately 250 W/m Kelvin to 5-8 W/m Kelvin. The aluminum cover provides superior mechanical shock resistance, ensuring the exhaust system remains safe and reliable under high-temperature operation.
5. Surface Polishing
The exhaust pipe surface undergoes a fine polishing process, reducing surface roughness to below one micrometer, thereby minimizing particle adhesion and dirt accumulation. The polished aluminum alloy surface offers enhanced corrosion resistance, remaining stable even in environments exposed to rain, dust, and moderate chemicals, and is less prone to corrosion pitting.
6. Optimized Structural Weight
The entire exhaust system weighs approximately five kilograms, significantly lighter than traditional steel exhausts which typically weigh seven to eight kilograms. This lighter weight contributes to improved vehicle inertia and handling efficiency. The reduced weight also decreases the load on the rear of the vehicle, making high-speed steering more agile, especially suitable for sporty and street riding scenarios.
1. Daily Street Riding
The Dual Outlet Motorcycle Exhaust is suitable for daily urban commuting. The dual-outlet exhaust allows for smoother acceleration and more linear power delivery in the low-end RPM range. For street bikes with displacements of 250-1500cc, improved exhaust flow reduces carbon buildup, helping to maintain engine stability.
2. Mountain Roads or Cornering Environments
In winding road conditions, vehicles require higher acceleration response and weight distribution. This exhaust weighs approximately 5kg, about 20% to 35% less than a standard steel exhaust, reducing the load on the vehicle at higher speeds. The reduced weight improves lean transition speed, giving riders greater agility in continuous corners, and the more stable exhaust temperature distribution helps maintain the durability of vehicle components.
3. Track and Recreation Riding
For informal racing or track riding experiences, the dual-outlet structure allows for smoother exhaust flow in the mid-to-high RPM range, reducing exhaust back pressure by 20% to 30%. This effect allows the vehicle to accelerate faster in the later stages, improving power delivery and providing stronger power sustain during straight-line acceleration or sharp corner exits.
4. Long-Distance Cruising
For long-distance riding, the exhaust system needs to be stable, heat-resistant, and low-noise. The aluminum alloy exhaust dissipates heat quickly, allowing the exhaust casing temperature to drop more rapidly after extended operation. The dual-outlet design also reduces exhaust sound pressure peaks, making it more suitable for prolonged use without generating excessive noise.
5. Appearance Upgrades
The Dual Outlet Motorcycle Exhaust features a distinctly sporty design, with the dual-outlet structure giving the rear a more mechanical look. The polished surface ensures a uniform finish and high color consistency. For users seeking to upgrade their vehicle's appearance, this exhaust provides a significant visual enhancement while maintaining functionality, meeting the demands of the aftermarket.
Although different brands and models of Universal Slip-on Motorcycle Exhaust may differ in installation details, the following is a rough guide to the installation steps:
Prepare tools: Before installation, make sure you have prepared the necessary tools, such as screwdrivers, wrenches, rubber hammers, etc. At the same time, make sure your motorcycle is in a safe state, such as turning off the engine and removing the key.
Check accessories: Unpack the Universal Slip-on Motorcycle Exhaust and check whether all accessories are complete, including the exhaust pipe body, connectors, fixing screws, etc.
Locate the exhaust pipe: Park the motorcycle on a flat ground and find the connection position of the original exhaust pipe. Make sure that the Universal Slip-on Motorcycle Exhaust can be correctly aligned with these connection positions.
Remove the original exhaust pipe: Use appropriate tools to remove the original exhaust pipe. During the removal process, take care to protect other parts of the motorcycle from damage.
Install the new exhaust pipe: Slide the Universal Slip-on Motorcycle Exhaust onto the exhaust system of the motorcycle and make sure its connector fits tightly with the exhaust port of the motorcycle. Use the provided fixing screws to secure the new exhaust pipe in place. When tightening the screws, be careful to maintain the proper force to avoid damaging the exhaust pipe or exhaust system.
Check the installation: After installation, carefully check that all connections are secure and reliable. Make sure there are no loose connections or leaks. At the same time, start the motorcycle and check whether the exhaust sound and power output are normal.
Adjustment and optimization: If you find that the exhaust sound or power output is not as expected during use, you can make appropriate adjustments and optimizations as needed. For example, adjust the angle or position of the exhaust pipe to improve airflow and performance.
This exhaust is compatible with most mainstream motorcycles, with a 51mm connector diameter, including common street and sport motorcycles such as the Yamaha YZF series, Suzuki GSX series, and Honda CBR 250. Users are advised to check the tailpipe connector diameter before installation to ensure compatibility.
The product uses a standard 51mm connector and comes with a mounting bracket, usually allowing direct replacement of the original exhaust. If the original exhaust has a non-standard diameter, an adapter may be required. Most users can complete installation within 10-20 minutes; professional installation takes even less time.
The aluminum alloy body undergoes surface polishing and protective treatment, making it less prone to significant oxidation under normal use. Users are advised to clean it regularly and avoid prolonged contact with strong acids or alkalis to maintain surface stability.
Dual-outlet exhausts offer a more balanced sound pressure distribution, and the noise peak is more controllable compared to single-outlet exhausts. Although the sound will be more focused, it will not significantly increase the noise level, making it a suitable solution for balancing daily use and performance upgrades.
