Old-school exhaust line for Triumph T100/T120

Old-School Exhaust System – Triumph Classic after 2016

Straight vintage-style exhaust — Fibonacci Spiral structure, mirror-polished or brushed

Give your modern Triumph the authentic soul of the early T-series with this old-school straight exhaust line, hand-built as a tribute to true classic motorcycles.

Each piece is individually crafted to deliver a unique presence and an unmistakable retro signature.
