AKRAPOVIC S-T4SO1-HDT Triumph Speed 400 (2024+) Slip-On Exhaust (titanium)
Slip-on exhaust (titanium) Triumph Speed 400 by AKRAPOVIC.
The neo-retro styling utilizes a muffler design first introduced thirty years ago and featuring many updates since then.
This Slip-On Line (Titanium) perfectly integrates with the lines of the bike.
It is constructed with a high-grade sandblasted titanium muffler outer sleeve, and the link pipe, end cap with imprints, heatshield, and muffler inner structure are all made from stainless steel.
It is finished with a monochrome logo sticker and a heatshield to prevent burning or damage to the rider’s gear.
During the development stage, emphasis was placed on throttle response and performance.
It delivers increases in power and torque of 0.7 kW (0.9 hp) at 8,000 rpm and 1.0 Nm at 8,000 rpm, respectively, when compared to a Triumph equipped with a standard stock exhaust system and tested on the Akrapovič in-house dyno.
Lightweight materials create a weight reduction of 39.5% (1.3 kg) against the standard stock system.
This product has a deep and full sound. It is EC/ECE type approved and Euro5 compliant, and the straightforward plug-and-play installation means no remapping is needed.
