Akrapovic Track Day Slip-On Silencer Titanium – Yamaha YZF-R1/M (2015-2026) S-Y10SO19-RT/TD

Engineered specifically for track-day regulations where noise limits are strictly enforced, the Akrapovic Track Day Slip-On Line in titanium is the benchmark choice for Yamaha YZF-R1 and YZF-R1M riders who refuse to compromise on compliance or performance. Every component — from the hexagonal titanium silencer shell to the internal workings — is constructed from race-proven titanium, keeping weight to a minimum while meeting the tighter sound thresholds demanded at circuits across the world.

Key Features

• Designed to meet stricter circuit noise regulations, making it the go-to solution for track-day and club-racing events where standard systems are prohibited
• Hexagonal silencer body with a 60 mm connection, constructed entirely from titanium including all internal components — no compromises on build integrity
• Carbon fibre end cap and carbon mounting bracket and clamp deliver additional weight savings and a purposeful, race-ready aesthetic
• Direct fitment to the original header pipe — no modification to the stock exhaust manifold required
• Must be paired with link pipe L-Y10SO11T/TD (for the standard header) or L-Y10E5/TD (for Evolution Line or Racing Line headers); refer to the respective link pipe listings for noise level data
• Mounting kit P-MBY10E2 (silencer bracket and clamp) is required and must be ordered separately — available as a bundle option above

Build Quality and Materials

Akrapovic's reputation in MotoGP and World Superbike is built on titanium craftsmanship, and the Track Day Slip-On carries that pedigree directly to the street-to-circuit rider. The silencer shell is formed from aerospace-grade titanium, prized for its exceptional strength-to-weight ratio and resistance to the thermal cycling that destroys lesser materials over a full track day. The carbon fibre end cap is not a styling flourish — it is a functional heat shield that also trims grams from the tail end of the machine. All metallic internals share the same titanium specification, ensuring consistent thermal behaviour and longevity under sustained high-rpm use.

Track-Day Compliance and Intended Use

This system has been developed expressly for venues that operate under reduced noise limits — circuits where a full race exhaust would exceed the permitted dB threshold and result in exclusion from a session. By pairing the Track Day silencer with the appropriate Akrapovic link pipe, riders can tailor the sound output to the specific requirements of their circuit. Noise level figures are published in the individual link pipe product descriptions. It is important to note that this product does not meet emissions standards for road or motorway use and is intended solely for closed-circuit track riding.

Fitment and Compatibility

This silencer is designed and tested to fit the following motorcycles:

• Yamaha YZF-R1 — 2015 to 2026
• Yamaha YZF-R1M — 2015 to 2026

Connection: 60 mm slip-on interface compatible with the stock header. Link pipe required — choose L-Y10SO11T/TD for the standard factory header or L-Y10E5/TD when running an Akrapovic Evolution Line or Racing Line header. Mounting kit P-MBY10E2 must be ordered separately (or selected as a bundle at checkout).
