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)
