DescriptionThe whole story▼

The Akrapovic Slip-On Line in titanium is one of the most accessible upgrades you can make to a Yamaha YZF-R1 or R1M, delivering a genuine gain in power and torque without the commitment of a full-system swap. Compatible with Euro 4 and Euro 5 models from 2015 through 2026, it bolts straight onto the original header and carries full EC type approval for road use.

Key Features

  • Measured power increase of +1.5 hp over the stock exhaust (197 hp at 14,000 RPM versus the standard 195.5 hp)
  • Torque improvement of +0.8 Nm at 12,450 RPM for stronger mid-range response
  • Hexagonal silencer canister with full titanium shell, titanium end cap and titanium internals throughout
  • Designed to mate directly with the factory Yamaha header — no additional modifications required
  • Carbon heat shield included in the box, adding a premium visual touch straight out of the packaging
  • EC type approval for Euro 4 and Euro 5 compliance — fully road-legal across European markets

Everyday Usability and Real-World Value

Where full exhaust systems demand additional mapping, gasket sets and often specialist fitting, the Slip-On Line keeps things straightforward. Because it works with the original Yamaha pre-silencer, a dB killer is not required as standard — the setup is road-legal and immediately usable. For riders who want a measurable performance gain, a race-derived aesthetic and the unmistakable Akrapovic soundtrack without stripping the bike down to its frame, this is the logical choice.

The all-titanium construction keeps unsprung weight to a minimum and resists corrosion season after season. The hexagonal profile is lifted directly from Akrapovic's Grand Prix programme, so the R1 gains a genuine motorsport visual identity that stock exhausts simply cannot replicate. If track days call for a quieter exit, the optional dB killer (sold separately) can be fitted in minutes.

Construction and Finish

Every metallic component of the silencer — shell, end cap and the internals — is manufactured in titanium. This is not a titanium-wrapped silencer over a steel core; the material runs all the way through, which keeps the assembly light and means heat management is consistent across the full surface area. The carbon fibre heat shield provides thermal protection and completes the look with the same materials seen on Akrapovic's World Superbike and MotoGP equipment.

Fitment and Compatibility

This slip-on silencer fits the following models:

  • Yamaha YZF-R1 — model years 2015 to 2026 (Euro 4 and Euro 5)
  • Yamaha YZF-R1M — model years 2015 to 2026 (Euro 4 and Euro 5)

Installation uses the existing Yamaha header pipe. No additional mounting brackets or header modifications are needed.
