Product details
Akrapovic Complete Exhaust System Set S-A6R4-HAPC For Aprilia 660
The Racing Line is the perfect upgrade for riders who want a serious performance boost without stepping up to a full Evolution system. It represents a complete step forward in exhaust tuning, delivering an ideal balance between price and maximum performance.
Designed for riders who demand more from their motorcycle, the Racing Line system is significantly lighter than the stock exhaust, improving overall handling and responsiveness. Built with exceptional production quality, it enhances engine performance while producing a pure, aggressive racing sound.
Featuring premium racing materials such as a carbon fibre muffler outer sleeve, this system adds a true motorsport look to match its performance gains.
Key Features:
- Full Racing Line exhaust system
- Noticeable weight reduction over stock
- Improved engine performance
- Sharper throttle response
- Pure racing sound
- Carbon fibre muffler outer sleeve
- High-quality, race-inspired construction

Solid steps show periods confirmed by the store’s change-only price history and completed crawl record: if the price had changed at a check, another point would appear. Dashed steps show overdue periods with no completed crawl confirmation. Every line stops at that listing’s last confirmed check and is never extended to today. Prices are not live and may have changed since the last point shown.
