Extended Product Information
FAQs
Does this part include the silencer?
No, the ARROW 71777MI is specifically a collector component designed to connect the cylinder head to the silencer.
Do I need to tune my ECU after installation?
It is highly recommended to tune your ECU or install a fuel management module to account for the increased exhaust flow and prevent a lean-running condition.
Is this road-legal?
These collectors are designed for racing purposes and typically remove emissions-related components, making them unsuitable for street use in most regions.
Can I install this with my stock exhaust muffler?
These collectors are designed to be interchangeable with the original; however, check for specific connection diameter compatibility with your current silencer.
What is the primary material used?
ARROW utilizes high-grade, durable materials selected for heat resistance and weight optimization.
How often should I inspect the springs?
Inspect the springs during every oil change or after every track event to ensure they maintain proper tension.
Troubleshooting
Exhaust leak sound near the engine block
Ensure the exhaust gaskets are seated correctly and that the flange nuts are tightened to the manufacturer's specified torque settings.
Engine feels like it is misfiring at high throttle
The increased airflow requires a richer fuel mixture; check that your ECU map or fuel controller is adjusted for racing exhaust systems.
Surface discoloration or bluing
This is a normal thermal reaction for high-performance exhaust materials and is not a defect.
Pros and Cons
Pros
- Significantly improves exhaust gas scavenging and engine efficiency
- High-quality construction ensures long-term durability under thermal stress
- Provides an aggressive, sport-oriented exhaust note
- Designed to be a direct replacement for the original OEM manifolds
Cons
- May require an ECU reflash or fuel controller for optimal fueling
- Not intended for street-legal use in jurisdictions with strict noise regulations
- Lacks the restrictive catalytic converters found on stock components
Setup, Compatibility & Care
Installation of the ARROW 71777MI should be performed by a qualified mechanic to ensure proper sealing of the exhaust ports and correct alignment with the rear silencer.
Compatibility: This part is designed to be interchangeable with the original collector; however, always verify your motorcycle's specific model year and sub-variant compatibility before purchase.
Maintenance:
- Regularly inspect the manifold springs and mounting bolts to ensure they remain tight, as vibration can cause them to loosen over time.
- Clean the exterior of the collectors with non-abrasive metal cleaners to prevent surface oxidation or road grime buildup.
- Periodically check the exhaust gaskets at the cylinder head interface and replace them if you notice signs of exhaust leaks, such as soot deposits.
