Racing Stage 3 Kit Aprilia RSV4 2025 (USA 2026) – Akrapovic Full System + UpMap + GRT Velocity Stacks + Sprint Filter

Product Description

The Racing Stage 3 Kit for Aprilia RSV4 2025 (USA 2026) combines four coordinated upgrades for a complete performance package. It brings together the Akrapovic S-A10E9-RC full exhaust system, the UpMap T800+, the GRT velocity stacks, and the Sprint Filter PM147S, optimizing intake, exhaust flow, and ECU management.

What’s Included

  • Akrapovic S-A10E9-RC full system (headers + silencer) in lightweight racing construction.
  • UpMap T800+ with Euro 5+ cable to load the dedicated calibration matching full system + stacks + filter.
  • GRT velocity stacks designed for RSV4 Euro 5+, improving cylinder filling and mid-to-top performance.
  • Sprint Filter PM147S high-flow, washable, and reusable performance air filter.

Dyno Gains (Typical Combined Results)

  • +6–13 HP at the wheel versus stock with the complete Stage 3 package and a dedicated UpMap calibration (range depends on fuel quality, ambient conditions, and exact mapping).
  • Noticeably stronger midrange torque and cleaner top-end pull thanks to reduced backpressure and improved volumetric efficiency.
  • Faster throttle response and smoother delivery across the rev range.

Important: do not attempt to sum individual component gains. The dedicated map aligns AFR, ignition, and ride-by-wire strategies to maximize the synergy of full system + stacks + filter.

Key Benefits

  • Increased power and torque across the rev range with cleaner delivery.
  • Quicker throttle response and stronger midrange driveability.
  • Weight reduction versus the OEM exhaust layout.
  • Sportier racing sound consistent with the RSV4’s character.
  • Plug-and-play installation with the option to revert to stock.

Technical Details

  • Akrapovic full system: replaces OEM headers and silencer for maximum efficiency.
  • UpMap T800+: loads a dedicated map tailored to full system + GRT stacks + PM147S; includes OEM map backup/restore.
  • GRT velocity stacks: RSV4 E5+ specific, boosting high-rpm performance; map coupon included.
  • Sprint Filter PM147S: polyester media delivering high airflow with excellent filtration efficiency.

Compatibility

Valid exclusively for Aprilia RSV4 E5+ 2025 (USA 2026).

Installation and Resources

  1. Install the Akrapovic full system following the prescribed torque specs and sequence.
  2. Fit the GRT velocity stacks and replace the PM147S air filter.
  3. Connect UpMap, back up the OEM map, and load the dedicated calibration for this configuration.
  4. Verify alignment, sealing, and correct ECU recognition; perform final checks.

FAQ – Frequently Asked Questions

Do I need to remap the ECU?
Yes. Use UpMap to load the dedicated map that optimizes the full system, stacks, and filter while preventing electronic errors.

Is this kit street legal?
The Akrapovic full system is intended for racing use. Always check local regulations before road use.

Can I revert to stock?
Yes. All components are bolt-on; you can restore the OEM configuration at any time and reload the stock map via UpMap.
