The Invidia Gemini Exhaust System is precisely engineered to benefit vehicles with dual exhaust systems. Widely regarded as a true dual exhaust, the Invidia Gemini Exhaust System aims to take your engine's performance to a whole new level. This high-performance system is manufactured from heavy-duty mandrel-bent stainless steel tubing for superior resilience, minimized backpressure, and unrestricted airflow. The Invidia Gemini Exhaust System is crafted from high-quality mandrel-bent SUS304 stainless steel tubing and manufactured using TIG welding. This manufacturing process gives the system not only a polished finish for better aesthetics but also a superior corrosion resistance. Meanwhile, the large diameter piping ensures better engine breathability for enhanced throttle response, higher horsepower, and torque gains.

Aside from elevating the overall performance of the vehicle, Invidia's Gemini Exhaust System also generates that deep, toned exhaust sound. These Catback Exhaust Units are available in three different exhaust tip styles: the rolled stainless steel, rolled titanium, and straight titanium. Designed as a direct-fit and bolt-on system, the Invidia Gemini Exhaust System comes complete with the muffler section, mid-pipes, resonators, connector pipes, and all the necessary mounting hardware to ensure quick and hassle-free installation.
