Product Details
Developed as an upgrade to complete a full system when paired with the Akrapovič Slip-On Line (Titanium) exhaust, this header is constructed from high-grade titanium with a carbon-fibre heatshield. Intended exclusively for closed-course competition circuits only, it enhances performance and reduces weight.
Tubes with a bigger diameter than the standard stock system and removal of the catalytic converter allow for enhanced gas flow. The pre-muffler offers a unique sound experience, producing a deep racing tone from the boxer engine. This upgrade results in a 54.84% (3.4 kg) weight reduction compared to standard stock. When combined with the Slip-On Line (Titanium), it boosts power by 3.1 kW (4.2 hp) at 7,800 rpm and torque by 5.9 Nm at 3,000 rpm, as tested on the Akrapovič dyno against a BMW R 1300 R equipped with a standard stock system. Installation is plug-and-play, but remapping is mandatory.
The optional header is also compatible with the Akrapovič standard (first fit) / BMW Motorrad accessory Akrapovič silencer. With installation of the Optional Header (Titanium), ECE type approval for the Slip-On Line (Titanium) is no longer valid.
When installing the Optional Header on Euro5+ motorbikes (2 lambda sensors), the engine check light will appear after identifying a deviation in the stock catalytic converter´s parameters.
For perfect performance, rideability, and durability, special electronic equipment developed by Rapid Bike by Dimsport may be used.
This new device makes it possible to avoid potential check engine light issues while optimizing the power delivery, personalizing the riding experience, and offering a diagnostic tool to the user.
