Racing Stage 2.5 Kit for RSV4 2021-2024 (USA 2025) – SPARK Slip-On + UpMap + GRT Velocity Stacks + Air Filter

Product Description

The Racing Stage 2.5 Kit for Aprilia RSV4 2021-2024 (USA 2025 – Euro 5) combines four targeted upgrades to boost performance while keeping installation simple and fully reversible.
It pairs the SPARK Konix Evo slip-on, the UpMap device,
the GRT velocity stacks, and the Sprint Filter PM147S,
optimizing intake flow, exhaust efficiency, and ECU management for stronger torque, sharper throttle response, and a sportier soundtrack.

What’s Included

• SPARK Konix Evo slip-on designed to reduce weight and improve exhaust gas flow.
• UpMap T800+ with Euro 5 cable to load the dedicated map for this Stage 2.5 setup.
• GRT velocity stacks engineered for improved cylinder filling and cleaner mid-to-top performance.
• Sprint Filter PM147S high-performance, washable and reusable air filter.

Key Benefits

• Increased power and torque across the rev range.
• Quicker throttle response and smoother, fuller delivery.
• Weight reduction versus stock thanks to the slip-on silencer.
• Sportier sound in line with the RSV4’s racing character.
• Plug-and-play installation with an easy return to stock if needed.

Technical Details

• SPARK Konix Evo slip-on: integrates with OEM headers and catalyst for straightforward fitment.
• UpMap: loads a dedicated map to unlock the combined potential of slip-on, velocity stacks, and air filter.
• GRT velocity stacks: specific for RSV4 Euro 5, supporting stronger midrange and improved top-end.
• Sprint Filter PM147S: high airflow with excellent filtration efficiency.

FAQ – Frequently Asked Questions

Do I need to remap the ECU?
Yes. Use UpMap to load the dedicated map that optimizes the slip-on, velocity stacks, and air filter, avoids electronic errors, and maximizes performance.

Is the slip-on compatible with stock headers and catalyst?
Yes. The Konix Evo slip-on is designed to work with the OEM exhaust path, simplifying installation and the return to stock.

How does Stage 2.5 compare to Stage 3?
Stage 2.5 uses a slip-on. Stage 3 adds a full system, delivering further weight reduction and additional performance potential.

Final Notes

The Racing Stage 2.5 Kit RSV4 2021-2024 (USA 2025) is a balanced, reversible upgrade that enhances torque, power, and throttle response while preserving compatibility with the OEM layout of your Aprilia.
