Weight reduction and unrestricted exhaust flow are priorities for serious R33 GT-R builds. The Tomei Expreme Ti Titanium Exhaust System (part number TB6090-NS05B) is a full-titanium cat-back designed specifically for the Nissan Skyline R33 GT-R, engineered with competition use in mind and constructed from high-grade titanium throughout.
The system uses a straight, single-pipe layout with an 89.1 mm main pipe diameter and thin-wall 1 mm construction to maximize flow while minimizing mass. A carefully designed silencer and 115 mm tip help produce a strong performance exhaust note without unnecessary restriction. Slide joints replace traditional heavy flanges and gaskets in key areas, further contributing to the dramatic weight reduction—dropping the system to approximately 7.15 kg and saving more than 11 kg compared with the factory exhaust.
This Expreme Ti system is intended for performance and competition-oriented applications where lightweight construction and efficient exhaust flow are valued. At Terra Firma Automotive, we supply this genuine Tomei Titanium Exhaust as a high-end upgrade for R33 GT-R owners seeking substantial weight savings and improved exhaust performance. Whether the car is prepared for track use or a focused street build, this titanium system delivers the material quality and design approach associated with Tomei. Choose Terra Firma Automotive for authentic Japanese performance exhaust components that support serious Skyline GT-R projects.
