The R1 TITAN STTI-90 Catback Exhaust System for the Nissan Skyline GT-R BCNR33 and BNR34 is a premium full-titanium exhaust system manufactured in Japan and developed specifically to maximise the performance potential of the legendary RB26DETT engine.
Constructed from R1 TITAN’s high heat-resistant STTI titanium alloy, the system features a large 90mm straight-through exhaust design to maximise exhaust flow and minimise restriction. From the catalytic converter, the system transitions from an 80mm front flange directly into a 90mm pipe, maintaining a full 90mm internal diameter through the rear silencer.
Weighing just 4.9kg compared to approximately 18.1kg for the factory exhaust system, the STTI-90 delivers an impressive weight saving of approximately 13.2kg while providing the distinctive titanium exhaust note and motorsport-inspired appearance associated with R1 TITAN.
