Warning: Always follow the specific installation instructions provided by SC Project for your exact exhaust model. The general guidelines above should be supplemented with model-specific directions.
Frequently Asked Questions
The 51mm designation refers to the internal diameter of the exhaust pipe. This measurement is critical because it determines the exhaust gas flow capacity of the system. A 51mm diameter is considered a performance-oriented size that allows for improved exhaust gas flow compared to smaller stock exhaust systems. This enhanced flow helps reduce back pressure in the engine, potentially improving horsepower and torque while creating a more aggressive sound profile.
No, a 51mm exhaust is not universally suitable for all motorcycles. The appropriateness depends on several factors:
- Engine Displacement: Larger engines generally benefit more from wider exhaust diameters
- Engine Tuning: Modified engines may require specific exhaust dimensions for optimal performance
- Riding Purpose: Racing applications have different requirements than street riding
- Motorcycle Make/Model: Different motorcycles have varying exhaust port sizes and configurations
A 51mm exhaust might be too large for smaller displacement engines (under 400cc), potentially reducing low-end torque. For optimal performance, consult with professionals or refer to manufacturer recommendations for your specific motorcycle model.
SC Project is a premium Italian motorcycle exhaust manufacturer known for producing high-performance exhaust systems used in MotoGP, World Superbike, and other racing competitions. Their exhaust systems are characterized by:
- Lightweight Construction: Using materials like titanium and carbon fiber to reduce motorcycle weight
- Performance Enhancement: Engineered to improve horsepower, torque, and throttle response
- Distinctive Sound: Creating deep, aggressive exhaust notes that enhance the riding experience
- Racing Heritage: Developed and tested in competitive motorcycle racing environments
- Premium Aesthetics: Featuring distinctive designs that enhance motorcycle appearance
SC Project exhausts are available in various configurations including full systems, slip-ons, and headers, with both street-legal and racing-only options to suit different riding needs and regulatory requirements.
Performance improvements from an SC Project 51mm exhaust typically range from 5-15% in horsepower and torque, depending on your motorcycle model, existing modifications, and whether you're installing a slip-on or full system. For optimal results, pair the exhaust with an ECU remap or fuel controller to adjust air/fuel ratios appropriately. Weight reduction from replacing a stock exhaust with an SC Project titanium or carbon fiber system can range from 3-10 pounds, which improves handling and acceleration.
Titanium exhausts develop a distinctive blue/purple coloration with heat cycling, which is normal and often desirable. To maintain appearance: clean with mild soap and water when cool, avoid abrasive cleaners that can scratch the surface, apply a specialized titanium protective coating every 3-6 months, and wipe down after riding in wet conditions to prevent water spots. If you prefer to restore the original silver appearance, specialized titanium polish products are available, though this will remove the natural heat coloration.
