High-Mount Exhaust for Triumph Speed 400 & Scrambler 400 X

High-level exhaust that unleashes the style and sound of your 400 cc

Specifically engineered for the Triumph Speed 400 and Scrambler 400 X, this right-side high-mount exhaust draws its inspiration from desert-sled builds.

It frees up the swing-arm area, increases ground clearance and delivers a deep growl that flatters the 398 cc single without becoming obnoxious.
