True Dual 60mm Design:

The Invidia Gemini features a true dual exhaust design with 60mm (2.36") piping throughout. This larger diameter compared to the factory exhaust dramatically reduces backpressure and allows the VQ37VHR engine to breathe freely. The result is proven power gains, improved throttle response, and enhanced exhaust note.

Mandrel-Bent SUS304 Stainless Steel:

All piping is mandrel-bent to maintain consistent internal diameter throughout each bend, eliminating the crimping and restriction that occurs with crush bending. The SUS304 stainless steel construction provides exceptional durability, corrosion resistance, and heat tolerance. This premium material ensures the exhaust maintains its appearance and performance even after years of use.

Single-Layer Titanium Tips:

The single-layer titanium tips feature a stunning burnt titanium finish that adds a premium, high-end appearance to your 370Z. The 101mm (4") diameter tips fill the rear bumper cutouts perfectly and create an aggressive, purposeful look. The titanium construction is lightweight and corrosion-resistant, maintaining its appearance over time.

Aggressive Exhaust Sound:

The Invidia Gemini delivers an aggressive, deep exhaust tone that enhances the VQ37VHR's natural character. The sound is throaty and purposeful during acceleration, with a refined tone during cruising. It's loud enough to be exciting but not obnoxiously loud for daily driving. No drone at highway speeds.

Proven Power Gains:

Dyno testing shows the Invidia Gemini delivers +15 HP and +12 lb-ft torque on a stock 370Z. These gains come from the improved exhaust flow and reduced backpressure. When combined with other modifications (intake, headers, tune), the gains are even more significant as the exhaust supports higher power levels.

Direct Bolt-On Installation:

The Gemini is designed as a direct bolt-on replacement for the factory cat-back exhaust. No cutting, welding, or modifications are required. The system uses factory mounting points and includes all necessary gaskets and hardware for a straightforward installation.
