Reducing exhaust weight and improving flow are proven ways to sharpen the response of an S13 chassis. The Tomei Expreme Ti Full Titanium Muffler (part number TB6090-NS08A) is a single-exit cat-back system engineered for the Nissan Silvia, 180SX, and 240SX (R)PS13 platforms equipped with either the SR20DET or KA24DE engine. Built entirely from titanium, it delivers substantial weight savings and a high-flow layout suited to performance-oriented builds.
The system uses 80 mm main piping with a 1.0 mm wall thickness and follows a straight, competition-focused design that minimizes bends and restrictions. A large 152 mm silencer and approximately 115 mm tip complete the assembly, producing a sharp, purposeful exhaust note. Total system weight is only 4.65 kg—dramatically lighter than the factory steel exhaust—helping reduce rear-end mass and improve overall vehicle dynamics. A removable sound reducer is included, allowing owners to moderate volume for street driving or noise-restricted events.
Designed for enthusiasts who value both performance and authenticity, the Expreme Ti system combines lightweight titanium construction with Tomei’s racing-derived exhaust engineering. At Terra Firma Automotive, we supply this genuine Tomei Full Titanium Muffler as a premium upgrade for S13 owners seeking measurable weight reduction, improved exhaust efficiency, and a distinctive titanium finish. Choose Terra Firma Automotive for authentic Japanese performance exhaust components that deliver real results on the SR20DET and KA24DE platforms.
