Tomei Titanium Cat-Back Exhaust System (Mazda RX-8) (TB6090-MZ07A)

Tomei Titanium Cat-Back Exhaust System (Mazda RX-8)

This new full titanium exhaust system, proudly developed and released under the TOMEI name, enhances everything that makes the RX-8 special. Built with today’s technology, it celebrates the car’s 20-year legacy with performance that elevates the experience.

Highlights include:
Dramatic weight savings (OEM: ~18kg → TOMEI: 5.7kg)
Increased exhaust diameter (60mm → 80.5mm) for optimal flow
Lightweight, thin-wall titanium construction for strength, sound, and durability

Rather than chasing trends, we chose purpose. The TOMEI RX-8 exhaust features a single-exit layout for performance-oriented reasons:
Lighter than a dual-exit system
Straighter exhaust flow for cleaner acoustics
Tuned specifically for the rotary’s high-revving characteristics
This design is also a tribute to Mazda’s engineers—a quiet dialogue among creators who understand what matters most.
