Kit Racing Stage 2.5 RSV4 E5+ 2025 (USA 2026) Arrow Decat 71806MI Stacks Filter UpMap

The Kit Racing Stage 2.5 RSV4 E5+ 2025 (USA 2026) combines the UpMap T800+ ECU device, the titanium Arrow racing decat header 71806MI, the Gabro Racing Team velocity stacks kit and the Sprint Filter PM147S P08 air filter. This racing package is developed around the latest Aprilia RSV4 1100 E5+ 2025 (USA 2026) to improve exhaust flow, intake efficiency and engine management for riders looking for a complete Stage 2.5 upgrade on track.

Description

This Stage 2.5 racing kit is designed for RSV4 owners who want a coherent configuration: a decat Arrow racing header (cod. 71806MI) that removes the catalytic converter, a high flow Sprint Filter PM147S in the stock airbox, dedicated Gabro Racing Team intake stacks and the UpMap T800+ to load Gabro Racing Team ECU maps. The result is a freer exhaust, better breathing at high rpm and a calibration tailored to this hardware, with stronger acceleration, quicker throttle response and a more linear power curve in racing use.

The filter is washable and reusable, easy to maintain and ideal for riders who want a constant performance level over time. Product page: Sprint Filter PM147S P08 Air Filter for RSV4.

Key Benefits

Complete Stage 2.5 racing solution for Aprilia RSV4 1100 E5+ 2025 (USA 2026), combining ECU management, intake and exhaust in a single coherent kit.
Significant high rpm performance gain thanks to the Gabro Racing Team velocity stacks (+3-4 hp from 11,000 rpm to limiter) and the decat Arrow header 71806MI that maximises exhaust flow.
Sharper throttle response and smoother delivery due to optimised intake geometry, high flow P08 air filter and Gabro Racing Team maps loaded via UpMap T800+.
Reduced weight with the Arrow titanium decat header 71806MI, which removes the heavy catalytic section and offers a significant weight saving compared to the stock component.
High flow filtration with protection from the Sprint Filter PM147S, which keeps the engine safe while allowing the RSV4 to breathe more freely.
Smart ECU control: UpMap lets you back up the original map, load dedicated Gabro Racing Team calibrations, clear DTC errors and monitor engine parameters directly from your smartphone.

Technical Details

UpMap T800+: Bluetooth ECU interface for RSV4 / Tuono V4 E5+ 2025 (USA 2026). Includes original map backup and a Gabro Racing map (value €118) via GRTMAP coupon, with the option to purchase additional maps such as Track, MTorque, Stacks and Airbox. Includes OBD cable and automatically completes throttle and handle learning and error clearing after writing.
Arrow racing header 71806MI: titanium construction, decat design that removes the catalyst and exhaust valve section. Developed specifically for RSV4 / Tuono V4 EU 2025 (USA 2026) for track use only. Designed to improve power, torque and sound while reducing weight.
GRT velocity stacks: Manufactured in PA12 using advanced 3D printing, plug and play on the stock RSV4 airbox. Custom length and shape for front and rear banks, with a typical gain of +3-4 hp at high rpm. Supplied with a €168 coupon for the dedicated “STACKS” UpMap ECU map.
Sprint Filter PM147S: P08 polyester filtration element, washable and reusable, with increased airflow compared to traditional cotton or foam filters. Specifically designed for RSV4 models from 2015 onwards, including RSV4 1100 E5. Suitable for road and track use when used as a standalone component.
Use: the presence of the Arrow decat header 71806MI and racing ECU maps means the Kit Racing Stage 2.5 RSV4 E5+ 2025 (USA 2026) is developed for closed circuit use only and is not approved for public road traffic.

Compatibility

This Kit Racing Stage 2.5 is configured specifically for:

Aprilia RSV4 1100 E5+ EU 2025
Aprilia RSV4 1100 E5+ USA 2026

The individual Sprint Filter PM147S air filter is compatible with RSV4 models from 2015 onwards, but this complete Stage 2.5 kit is designed and recommended for the RSV4 1100 E5+ 2025 (USA 2026) platform.

Installation And Tuning Notes

Installation involves fitting the Arrow decat header 71806MI, replacing the stock air filter with the Sprint Filter PM147S and installing the GRT velocity stacks in the OEM airbox. For a racing configuration of this level, professional installation is strongly recommended.
Because the Arrow header 71806MI removes the catalytic converter, related sensors and the exhaust valve, using UpMap T800+ with dedicated Gabro Racing Team maps is essential to avoid error messages and to restore a correct air fuel ratio in racing use.
After installing the hardware, back up the stock ECU map with UpMap, then redeem the GRTMAP coupon and the coupon included in the GRT stacks kit to download the appropriate “STACKS” map and any additional Gabro Racing Team calibrations for your setup.
Use a battery charger or maintainer during ECU writing to prevent voltage drops. After flashing, verify that the engine runs correctly and check for stored DTC codes with the UpMap app.

FAQ

Which maps should I use with the Kit Racing Stage 2.5? With this configuration (Arrow decat header 71806MI, GRT stacks and PM147S filter) you should use Gabro Racing Team maps developed for RSV4 E5+ 2025 with racing exhaust and modified intake. The UpMap T800+ includes a Gabro map via GRTMAP, and the GRT stacks kit adds a €168 coupon for the dedicated “STACKS” map so you can build a map package that matches your Stage 2.5 hardware. Is the Kit Racing Stage 2.5 RSV4 E5+ street legal? No. The Arrow racing header 71806MI removes the catalytic converter and exhaust valve, and the ECU maps are designed for competition. This kit is intended exclusively for track and closed circuit use and is not homologated for public road traffic. Can I keep the original silencer with this kit? Yes, the titanium Arrow racing decat header 71806MI is compatible with both aftermarket silencers and the original RSV4 exhaust. Can I revert my RSV4 to stock after installing the kit? Yes. You can refit the original catalytic header, reinstall the OEM stacks and air filter and use UpMap T800+ to restore the factory ECU map saved during the first connection. This allows you to switch from the Stage 2.5 racing configuration back to the standard setup whenever necessary.
