Invidia 2015+ WRX/STi Gemini 80mm Full Titanium Quad 101mm Tip Cat-Back Exhaust

The Invidia R400 Gemini Full Titanium Exhaust is the ultimate evolution of Invidia's acclaimed R400 lineup. Taking the aggressive tone and high-performance layout of the standard R400 and refining it through aerospace-grade materials, this system is built for enthusiasts who demand the absolute best — in weight savings, sound, and visual impact. From daily drivers to track builds, this titanium variant delivers elite performance in every category.

Constructed entirely from high-grade Ti, the R400 Gemini Titanium system dramatically reduces weight over its stainless counterpart — often shaving 10-15 lbs or more, depending on application. Every inch of this exhaust is titanium mandrel bent and precision TIG-welded, offering not only exceptional durability under high temperatures but also a stunning burnt blue hue at the tips and welds. This is a showpiece-level part designed to perform.

Its performance is matched by its distinct sound profile: thanks to the multi-chambered, straight-through muffler design, the Gemini R400 Ti produces a sharper, more exotic note than stainless, with higher-frequency resonance that sings as you climb through the revs. Interior drone remains minimal due to thoughtful muffler geometry, while the exterior tone retains the rich, tuned growl R400 systems are known for.
