Introducing the Yoshimura AT2 Full Titanium Race Series Exhaust system engineered specifically to pair with our high-end Triumph engine packages, for the Triumph 765 triple cylinder. Developed and built in Chino, California, this closed-course racing exhaust is optimized to maximize the power potential locked inside your three cylinder race machine.

Key Features:

• Full Titanium Build: Crafted from premium Japanese titanium alloy
• Massive Weight Reduction: Drastically lighter than the stock OEM setup, trimming down several pounds to immediately improve motorcycle agility and side-to-side handling.
• Aggressive End Cap: Features a signature, matte carbon fiber end cap with an angular, facet-formed inner design.
• Carbon Fiber Heel Guard: Includes a matching matte carbon fiber heat shield heel guard is functional and looks incredibly clean.
• O2 Sensor Integration: Outfitted with professional M18 lambda sensor bungs directly on each header tube and mid-pipe for precise aftermarket data-logging and ultimate ECU tuning.
• Designed to work with Race bodywork and race oil pan routing.

Performance & Sound Dynamics:

• Optimized Power Gains: With the engine package this system adds up to 15.5% @11,000 rpm and up to 15% more torque @11,000 rpm
• Tunable Acoustics: Delivers the distinctive, fierce Yoshimura exhaust note that amplifies the unique British three-cylinder "triple howl". It will accommodate an optional sound insert kit if track day decibel limits require sound reduction.
• Race Engine Matching: While it can run on stock mapping, the system geometry is tailored to unlock maximum performance when paired with Yoshimura's complete race engine package.

Weights:
Stock exhaust: 21.0 lbs.
AT2 Race Series: 9.3 lbs.

Critical Installation Note:

Because of its specialized racing routing on the Triumph 765 platform, this full titanium system cannot simply replace a stock street exhaust. To achieve proper physical clearance, it explicitly requires the installation of Yoshimura's complete race engine package or specific matching racing components, including an updated factory oil pan (Part #T1230118), specialized gasket (Part #T1230129), and oil pick-up (Part #T1210282)
