Kit Racing Stage 3.5 Tuono V4 1100 E5+ 2025 (USA 2026) Arrow Header Titanium 71806MI Airbox Stacks UpMap

The Kit Racing Stage 3.5 Tuono V4 1100 E5+ 2025 (USA 2026) is a complete racing package that combines a decat Arrow racing header, a Stage 3 airbox kit, Gabro Racing Team velocity stacks and the UpMap T800+ ECU device. Developed around the latest Aprilia Tuono V4 1100 E5+ platform, this Stage 3.5 configuration optimises the whole intake and exhaust system, improving airflow, exhaust gas evacuation and engine management for track focused performance.

Description

This Kit Racing Stage 3.5 Tuono V4 1100 E5+ 2025 (USA 2026) is designed for riders who want a coherent racing setup: a titanium decat racing header that removes the catalytic converter, a larger and better sealed Stage 3 airbox with Sprint Filter, dedicated GRT velocity stacks and an UpMap T800+ device to load Gabro Racing Team maps. The result is a freer flowing exhaust system, a more efficient intake and an ECU calibration tailored to this configuration, with stronger torque, better throttle response and smoother power delivery.

Kit Contents

• Arrow Racing Header Titanium 71806MI for Aprilia RSV4 / TUONO V4 EU 2025 (USA 2026)
  This titanium racing exhaust header replaces the OEM catalytic section (decat), optimising exhaust gas flow and increasing power and torque while delivering a significant weight saving compared to the stock catalytic component. It is developed specifically for RSV4 / Tuono V4 EU 2025 (USA 2026) and is designed for track use, requiring dedicated ECU mapping. It is compatible with the OEM silencer and with aftermarket slip-on silencers. Product page: Arrow Racing Header Titanium for Aprilia RSV4 / TUONO V4 EU 2025 (USA 2026).
• Gabro Racing Team Velocity Stacks Kit for Tuono V4 E5+ EU 2025 (USA 2026)
  Dedicated intake stacks kit for Tuono V4 1100 E5+ EU 2025 and USA 2026, engineered to improve airflow and throttle response. The 3D printed PA12 stacks provide about +2/3 hp and help eliminate dips and flat spots in the power curve, with plug and play installation inside the standard airbox. The kit includes a €168 coupon for the dedicated “STACKS” ECU map on UpMap. Product page: Gabro Racing Team Velocity Stacks Kit for Tuono V4 E5+ EU 2025 (USA 2026).
• Stage 3 Airbox Kit Aprilia Tuono V4 1100 E5+ 2025 (USA 2026)
  Stage 3 airbox based on the RSV4 RR/RF design and modified to fit Tuono V4, with larger volume, better shape and improved sealing compared to the OEM Tuono airbox. The filter sits in a better position with a larger effective surface, giving noticeable power gains at high rpm and improved torque at low and mid range with no drops in delivery. The kit comes pre assembled with connecting hoses and a Sprint Filter PM147S for high airflow and excellent engine protection.

• UpMap T800+ Aprilia RSV4 – Tuono V4 E5+ 2025 (USA 2026)
  The UpMap T800+ device allows you to remap the Aprilia ECU via Bluetooth directly from your smartphone, using Gabro Racing Team calibrations. It works on RSV4 and Tuono V4 E5+ 2025 (USA 2026 version) and includes two maps: the original stock map and a Gabro Racing map (value €118), downloadable with the GRTMAP coupon. It also supports additional maps (Track, MTorque, Stacks, Airbox) using the coupons included in ASpecialParts kits. The unit includes OBD cable and, after programming, automatically performs throttle and handle learning, clears errors and shows real time engine data in the app. Product page: UpMap T800+ Aprilia RSV4 – Tuono V4 E5+ 2025 (USA 2026).

Key Benefits

• Complete Stage 3.5 racing configuration for Aprilia Tuono V4 1100 E5+ 2025 (USA 2026), combining decat exhaust, high flow intake and dedicated ECU management.
• Improved power and torque thanks to the Arrow titanium racing header 71806MI that removes the catalytic converter and optimises exhaust routing, together with the larger Stage 3 airbox and GRT stacks.
• Smoother, more linear delivery as the Gabro Racing Team velocity stacks help fill the typical dips of the stock torque curve, especially in the mid and upper rev range.
• Sharper throttle response due to optimised intake geometry and Gabro Racing Team ECU maps loaded through UpMap T800+.
• Weight reduction with the decat Arrow header 71806MI, while maintaining compatibility with the OEM silencer and aftermarket slip-on silencers.
• Smart ECU control: UpMap lets you save the original map, load Gabro calibrations, clear DTC error codes and monitor engine parameters from your Android or iOS device.

Technical Details

• Racing exhaust header: Arrow titanium header 71806MI, decat design (replaces the OEM catalytic section), developed for RSV4 / Tuono V4 EU 2025 (USA 2026), track use only, compatible with the OEM silencer and aftermarket slip-on silencers, intended to maximise exhaust flow and performance.
• Stage 3 airbox kit: based on RSV4 RR/RF airbox, adapted to Tuono V4 with larger volume and improved sealing, flat top cover without upper injector protrusions, supplied with connecting hoses and Sprint Filter PM147S high flow air filter.
• Velocity stacks: GRT stacks manufactured in PA12 using advanced 3D printing, plug and play on the standard airbox, gain of about +2/3 hp and smoother response, supplied with a €168 coupon for the dedicated “STACKS” map on UpMap.

Installation And Tuning Notes

• Installation involves fitting the Arrow decat header 71806MI, replacing the OEM airbox with the Stage 3 kit and installing the GRT velocity stacks; professional installation is recommended for a racing configuration of this level.
• Because the Arrow header removes the catalytic converter, using UpMap T800+ with the correct racing map is essential to avoid warnings related to catalyst removal and to restore the correct AFR in racing use.
• After hardware installation, back up the OEM ECU map with UpMap, then use the GRTMAP coupon and the coupons included in the GRT stacks kit to download Gabro Racing Team maps that match your Stage 3 airbox, stacks and Arrow header configuration.
• Dyno results can vary from bike to bike and depend on the overall exhaust system and setup; always verify correct engine operation after flashing and check for any stored DTC codes using the UpMap app.

FAQ

Which maps should I use with the Kit Racing Stage 3.5?
Use the UpMap T800+ to save the original ECU map and then load Gabro Racing Team calibrations dedicated to the Stage 3 airbox, GRT stacks and decat racing exhaust. The purchase of T800+ includes a Gabro map via the GRTMAP coupon, while the GRT velocity stacks kit adds a €168 coupon for the specific “STACKS” map, so you can build a map package optimised for this Stage 3.5 configuration.

Is the Kit Racing Stage 3.5 street legal?
No. Due to the decat Arrow racing header and the dedicated racing ECU maps, this kit is intended exclusively for track and closed circuit use and is not approved for public road traffic.

Can I revert my Tuono V4 to stock after installing this kit?
Yes. You can refit the original exhaust and airbox components and use UpMap T800+ to restore the factory ECU map saved at the first connection. This allows you to switch back from the Stage 3.5 racing configuration to the standard setup whenever needed.

Do I need additional components to use this kit?
No extra hardware is strictly required beyond what is included in the Kit Racing Stage 3.5 Tuono V4 1100 E5+ 2025 (USA 2026), but a battery maintainer during ECU flashing and professional installation are strongly recommended to ensure reliability and maximum performance in racing use.
