Akrapovic Slip-On Line Muffler for 2023-2026 Triumph Speed 400 / Scrambler 400 X | Titanium | S-T4SO1-HDT

The Akrapovič Slip-On Line muffler S-T4SO1-HDT is a titanium slip-on exhaust for the 2023-2026 Triumph Speed 400 and Scrambler 400 X, replacing the heavy factory silencer with an Akrapovič titanium canister that bolts to the stock header.

One part covers both bikes. Triumph built the Speed 400 and the Scrambler 400 X on the same 398 cc single-cylinder platform with shared exhaust mounting, so the same Akrapovič muffler fits the roadster and the scrambler alike — worth knowing, because the two are listed separately almost everywhere and buyers often assume they need model-specific parts.

These are light, inexpensive, genuinely well-sorted small Triumphs, and the factory silencer is the heaviest single thing bolted to the back of them. Titanium takes real weight off a machine where it counts proportionally far more than it would on a larger bike, and it gives the single the deeper, harder note the stock system suppresses. Installation is a bolt-on job with hand tools and no fuelling changes.
