Gemini R400 Single Layer Cat-Back with Black Tips for the 2015-2021 Subaru WRX STI

The Invidia Gemini R400 Single Layer Cat-Back with black tips for the 2015-2021 Subaru WRX STI is the R400 Gemini in black tip finish. Same independent per-tip muffler configuration, same R400 aggressive tuning, same quad exit, black tips in place of titanium for builds where the darker finish is the right visual call.

DETAILS

• Gemini configuration
• Single-layer black finish tips
• R400 muffler tuning
• 304 stainless steel piping
• Quad exit layout
• Mandrel-bent throughout

The R400 Gemini on the STI is loud and reactive, the EJ257’s boxer sound through independent muffler bodies is one of the stronger exhaust experiences on the platform. Black tip finish is coated stainless for heat resistance at tip operating temperatures.

Black tips suit World Rally Blue, Sapphire Blue Pearl, and dark-colored STI builds where the contrast works better than the warm titanium tone. Same installation, same fit, same R400 Gemini performance as the titanium variant.

Why Choose Invidia

Invidia has been manufacturing performance exhaust systems in Japan since 1999, and in that time they have built a reputation that carries real weight in the tuning community. Every system is manufactured using SUS304 stainless steel and mandrel-bent tubing, which eliminates the flow restrictions and weak points that crush-bent alternatives introduce at every corner. Their in-house engineering team designs each application from scratch rather than adapting a generic template, which is why Invidia fitment is consistently tighter than the competition. The result is an exhaust that installs cleanly, seals correctly, and lasts. Invidia backs their products with a quality standard that is visible in the finish, the weld quality, and the hardware, details that reflect over two decades of refining the same core manufacturing process.

The RallySport Take

The black tip version is for STI owners whose build color calls for the darker contrast. We see it most often on WRB and white VA STI builds. Sound and performance are identical to the titanium version, this is a visual choice and a valid one. Fits the 2015-2021 Subaru WRX STI EJ257 VA chassis. R400 Gemini aggression regardless of tip color.
