The Akrapovic Track Day Muffler S-Y10SO19-RT/TD is a race-focused exhaust component developed for track use where reduced noise levels are required. Designed for select Yamaha applications, this Akrapovic muffler supports a controlled exhaust note while maintaining the performance-oriented character expected from a premium racing system. Its compact, competition-inspired design is intended for riders and teams seeking a dedicated track-day solution from a leading exhaust manufacturer. The manufacturer part number is S-Y10SO19-RT/TD, and the associated vendor part number is 1811-4052.
This muffler must be installed with the correct Akrapovic connection components. For mounting to stock headers, use Akrapovic link pipe part 1812-0325. For installation with the header set from the Akrapovic Evolution Line kit, use link pipe part 1812-0324. The muffler is also compatible with the Akrapovic Evolution Line system part 1810-2344 or Racing Line system part 1810-2758 when paired with the appropriate collector, headers, and related fitting hardware. These system components may include flanges, springs, inner sleeves, and lambda plugs, depending on the selected configuration.
A separate Akrapovic fitting kit, part 1861-1254, is required for installation. This kit includes the muffler bracket and clamp necessary to secure part 1811-4052. Confirm the motorcycle application, exhaust system configuration, and required connection parts before ordering to ensure proper fitment. The Track Day Muffler is intended to be used as part of a compatible Akrapovic exhaust arrangement rather than as a universal replacement muffler. Professional installation is recommended, especially when combining the muffler with aftermarket headers or a complete Evolution Line or Racing Line system. This product is supplied as the Akrapovic muffler component; compatible link pipes, headers, and fitting hardware are ordered separately unless otherwise specified.
