At DMG Motorsports, we present the Yoshimura AT2 Race Series Full Exhaust System (19660AP520) — a purpose-built, closed-course race system engineered specifically for the Triumph Trident 660 and Tiger Sport 660. Featuring stainless steel piping paired with a stainless muffler and a matte carbon fiber end cap, this AT2 system delivers the aggressive styling, sound, and performance Yoshimura racing products are known for. The Yoshimura 19660AP520 AT2 Race Series Stainless Full Exhaust with Stainless Muffler is made specifically for Triumph Trident 660 (2021-2024) & Tiger Sport 660 (2022-2024). Max HP is up 6.9% and max torque is up 1.3% compared to the stock system, while the weight savings is substantial, dropping almost half the weight of the stock system, with the AT2 Works Finish full system coming in at a nice 9.1lbs. A specially designed pre-muffler in the collector enhances power and adds a very unique exhaust note to the all-new British Trident. Built for racers who demand both performance and finish, the AT2 is proudly developed, designed and made in the USA.
