Akrapovic Evolution Line Titanium Full System Yamaha YZF-R1/M (2015-2026) S-Y10E6-APLT

Engineered to close the gap between road and track, the Akrapovic Evolution Line in full titanium transforms the Yamaha YZF-R1 and R1M into a sharper, louder, and measurably faster machine. Drawing directly on Akrapovic's Grand Prix racing programme, this 4-2-1 Evo-2 full exhaust system slashes 5.8 kg from the stock setup while unlocking an additional 9.8 hp and 9.7 Nm of torque — figures that redefine what a production R1 can do at the limit.

Key Features

• Massive weight saving of 5.8 kg — stock system weighs 11 kg, Akrapovic Evolution Line comes in at just 5.2 kg, lowering the centre of mass and sharpening handling response
• Peak power rises from 190.2 hp to 200 hp at 13,750 RPM, with torque up by 9.7 Nm at 11,500 RPM for a broader, more aggressive powerband
• 4-2-1 Evo-2 full titanium construction — header, silencer and end cap are all titanium for maximum strength-to-weight performance
• Lambda connection retained on the collector for straightforward compatibility with the standard ECU and mapping solutions
• Carbon heat shields included in the box, protecting the fairing and rider from radiant heat at sustained high revs
• dB-Eater supplied as standard, giving you the option of a slightly lower sound level when regulations require it

Track-Born Performance

The Evolution Line is Akrapovic's most race-relevant road-legal offering for the YZF-R1 platform. The 4-2-1 Evo-2 collector geometry was developed with superbike racing in mind: primary tube sizing and collector volumes are tuned to maximise scavenging efficiency across the R1's characteristically high-revving powerband. The result is not just a headline peak power number but a genuine mid-range uplift — the 9.7 Nm torque gain at 11,500 RPM means the power arrives earlier and harder through the corners, exactly where lap times are won.

At 105.1 dB (a 7.1 dB increase over the stock 98 dB figure), the sound signature is unmistakably race-bred — a crisp, titanium-tinged howl that builds with revs rather than droning at cruise. For track days where noise limits apply, the included dB-Eater can be fitted in moments without tools.

Construction & Materials

Every component of the S-Y10E6-APLT is purpose-built for the R1's compact chassis packaging. The full titanium construction — from the four primary headers through the twin collectors and into the end silencer — keeps the system extraordinarily light without any compromise in structural integrity under the sustained heat cycles of track use. The included carbon heat shields are shaped specifically for the YZF-R1 fairing profile, ensuring a clean installation with no gaps or fitment compromises. Installation is straightforward, following Akrapovic's step-by-step hardware kit designed for this exact model.

Fitment & Compatibility

This exhaust system is designed exclusively for the Yamaha YZF-R1 and YZF-R1M, covering model years 2015 through 2026. It is not compatible with other Yamaha models or earlier R1 generations. Always verify your model year and variant before ordering.
